ADACA Guide: Codes, Collectibles and Cool stuff

In this guide you’ll find information that might help you along when playing ADACA, from codes and locations with good loot to easter eggs and secrets. The guide is split into two sections, Campaign and Zone Patrol, with each section then split again into the various maps. Areas which aren’t found on the game map are described in the section of the map from which you can enter them.

PLEASE NOTE: Like the games ADACA takes inspiration from, this is a game about discovering things. The Zone Patrol mode in particular is structured around the idea that you’ll find bits and pieces of information and you’ll have to figure out where and how to use them. Thus, I suggest you only use this guide in those cases where you REALLY don’t know where to find something instead of just using this as a check list to work through. It’ll ruin your experience!

Zone Patrol – BEACH HEAD

BSMT-535 – A small basement in the building marked with the ‘SAVLO’ logo.
47217

Bum Leg – A sawn-off rifle with a bayonet. Fits into the sidearm weapons slot.
From the drop ship, turn due east. On the other side of the body of water, you’ll see a small wooded area, to the right of a set of stairs that lead down to an empty room. Within the wooded area, you’ll find a mannequin with the Bum Leg stuck into it.

Data Cache
From the drop ship, immediately turn west. You should be looking at a big tube-like structure lying on its side. You can enter it through the water and you’ll find the data cache inside.
Data Cache Reader
Follow the train tracks to the easternmost part of the map. Behind the warehouse-looking building, you’ll see a tiny building wedged between the power line pylon and the radar jamming tower. The reader is in the tiny building.

Target Locator – A locator for an artillery battery. Have fun!
Enter BRAVO 2 from NECROPOL. Move through the gate, then turn left immediately. The first little building you see has the Target Locator in it, immediately when you enter it, on a table to the left.

Mistake – A silenced, scoped assault shotgun.
Enter CATACOMBS from JUNCTION 06, follow the hallway and walk down the two short sets of stairs. You should now see writing on the wall showing the way to CISTERN, Lab 28 and ‘HWY’. To the right of the wall with the writing on it is one of those enclosed staircases clad in what look like white wooden boards. Enter and take the stairs down. Leave the enclosure on the lower level, and move around to the other side of the same enclosure. You should see Mistake leaning against the white wooden boards of the enclosure.

Ammo Bags – Doubles your maximum ammunition for all weapons.
Enter CATACOMBS from JUNCTION 06, follow the hallway and walk down the two short sets of stairs. You should now see writing on the wall showing the way to CISTERN, Lab 28 and ‘HWY’. Move along the gangway in an eastward direction. After a few steps, you should see an enclosed staircase clad in what looks like white wooden boards to your left. Enter and then go through the door opposite the stairs leading down. To your left, behind a bunch of boxes with a yellow cargo net is a shelf with the Ammo Bags.

Data Cache
Enter CATACOMBS from BLUE CAVERNS, follow the hallway, turn left and then take the second left. At the end of this hallway, there is a narrow passage blocked with some clutter. The passage leads into a room with some goodies and the data cache.
Data Cache Reader
Enter the CATACOMBS from STORM DRAIN and follow the markings on the walls to the Office. In the Office area, the data reader is on the eastern wall of the computer room, next to the room with the plants.

(Lab 28)
Nothing of interest here.

Nothing of interest here.

Node-03
Enter the Control Center in the eastern part of the CISTERN. The node is in the northwestern corner of the room.
Easter egg Purple Worm Statue
Enter CISTERN from BEACH HEAD. Move down the stairs, turn right in the big hallway and move forward. At some point, there will be two white cabinets to your left. There is a hole in the wall behind the cabinets, leading to a little room with the statue.

Hatch – A hatch on the ground near the exit to THE PIT in the east of the map.
See “Small Tower”.
Small Tower – A keypad on a small reddish-brown tower found in the northern part of the map, between the Data Center, the Dish and the exit to THE HAUNT.
8686 – this opens the hatch (see above).

Crossbow – A silent (?) crossbow with reusable bolts.
Move to the eastermost part of the map, near the exit to THE PIT (Free Scrappers base). There’s a building here with a ‘West Adacadian Mining Corp.’ sign on the side (the building you’ll need to enter to get to the Free Scrappers base). Get inside that building, then use clutter objects to make your way to its uppermost level. The Crossbow is lying on a table here and there are more bolts stuck in a mannequin opposite the table.
Pulsar – A 3-round burst fire variant of the Plasma Rifle, with a plasma torpedo secondary fire mode.
Make your way to the southern part of the map. You’ll find yourself on a road that’s partially covered in a tube-like structure, running from east to west. Follow that road to its westernmost point. There’s a Police drop pod there, right next to the road, with a corpse and the Pulsar weapon.
Special Rocket Rifle – An ordinary-looking Rocket Rifle but with a much larger explosion radius and more ammunition than the standard Rocket Rifle.
Make your way to the eastermost part of the map, near the exit to THE PIT (Free Scrappers base). There’s a building here with a ‘West Adacadian Mining Corp.’ sign on the side (the building you’ll need to enter to get to the Free Scrappers base). Go up the stairs, but don’t enter the building. Instead, turn around and jump on the brown pipes running from north to south. Move along the pipes to the south until you’re right in front of the red-and-white “water tower”. Jump up and you should see the special Rocket Rifle lying on top of that “water tower”. Use your gravity arm to grab it mid-jump.

Data Cache
???
Data Cache Reader
Use a battery to activate the lift to the Data Center in the northwestern corner of the map. Ride the elevator all the way up and enter the Data Center. The data cache reader is in the westernmost part of the Data Center, opposite the open window overlooking the area
Node-01
Use a battery to activate the lift to the Data Center in the northwestern corner of the map. Ride the elevator all the way up and enter the Data Center. The node is wedged in the southwestern corner of the second room (the one with the rows of computers in the middle of the room).

Data Cache
Make your way to the lower part of the map, with the big construction crane and the train tracks. Climb up the ladder on the construction crane to the top-most area you can reach. That’s where the data cache is.
Data Cache Reader

Easter Egg The Sword in the Stone – Not sure if this is a reference to something specific, other than Arthurian mythology maybe?
Go to THE PIT (Free Scrappers base) and make your way down the building until you’re on a gangway running along the building’s outside. Move to the southeastern corner of that gangway and you should see an outcrop in the rock wall. There’s a sword embedded in the stone there, but AFAIK, you can’t interact with it.

Easter egg Cube-Head – Don’t know what this is supposed to be either.
Go to CONCRETE FORSET via the hatch in THE DISH and enter the small room to the east. Go up to the Idol and turn right. There’s a part of server (?) wall that has something like a wooden board hiding a small air duct. Destroy the board and follow the air duct to a room with a grey cube-headed creature.

Door to The Bowels – A door with two neon green signs next to it.
032546

Node-04
Once you’ve entered THE BOWELS, move along the railing you see in front of you to the hallway on the right. Follow the hallway and move forwards at the first junction, then turn left. You’ll find yourself in an area with significantly less flesh on the walls. Take the stairs down to your right, then take the bridge to your left, then turn right and move up the stairs. If you’re here for the first time, you’re probably noticing the hallucinations. After the stairs, turn left, then right. Follow the hallway and destroy the hallucination emitting… thing… in the fleshy area. Now trace your steps back to where you just moved up the stairs. Turn left again, but instead of going right to the hallucination thing, there should now be an opened door in front of you (where you can see the blood on the ground). Node-04 is in the room behind this door.

Nothing of interest here… I mean, except for ALL THAT…

Data Cache
Go to the exit to the CATACOMBS in the southern part of the map. To the left of the building, behind some barrels and pipes, you’ll find the data cache.
Data Cache Reader
Go to Depot 6-B in the northeastern part of the map. Enter the building and move to the uppermost floor. The data cache reader is in the western part of the building.

BM-061 – A door in the room with the hallucinatory enemies.
9795

Red Weapons Chest
Enter BM-061 and follow the hallway until you enter the room with the hallucinatory enemies. Turn around and climb up one of the ladders on the wall. Once you’re up there, balance across the steel girders to the south until you reach a boarded-up door. Destroy the boards. The chest is in this room, along with an infinite ammo crate and an infinite grenades crate.

K-102 – A small underground area with a bunch of computers.
Go to the big ramp leading from the lower city to the upper city. Jump down the hole underneath the ramp. Move south until you reach the gangway. Turn west to enter K-102.

Arc Repeater – A slow-firing full-auto energy rifle with a low-power scope. The projectiles bounce off surfaces.
Enter THE PINES from JUNCTION 06 and follow the train tracks until you come to a train bridge. Turn right before the bridge and follow the beach to the northeast.

PV-09 Goggles – Goggles which replace your binoculars and highlight enemies, anomalies and artifacts through walls.
Enter THE PINES from JUNCTION 06 and follow the train tracks until you come to a train bridge. Crossing the bridge, you’ll see a train car to your left (this is part of camp B-1). The P-09 Goggles are on a table in this train car.

Easter egg Purple Worm Statue
Enter THE PINES from JUNCTION 06 and follow the train tracks until you come to a train bridge. Cross the bridge, then turn right and follow the beach. Towards the northern end of the beach, there will be an opening among the rocky outcrops which leads to the statue.

Locker Room Code
1234

Flame Thrower – A flame thrower, like you’d imagine it.
Enter OGR 018, follow the hallway with the fire anomalies and enter the door to the right. You’ll be in a hallway with a big brute enemy.

Node-05
Enter the Wolf Bunker, turn right in the room, then right again. Go down the stairs, then right again. You should now see an energy field in front of you. Enter the doorway on the right, then turn left again. Follow the hallway until you see a button-operated door on your left. Operate the button on the button-operated door to operate the door. Walk to the other side of the room, across the stairs leading down (don’t go down the stairs, stay on the same level!) and then go eastwards. You’ll see a broken door on your left that you can go through – Node-05 is on the left side of the room you’ll enter.

Pulse Rifle – Fires in bursts, with each burst from the same magazine being shorter than the last one.
Enter STAG BUNKER and follow the hallway. Turn right and enter the flooded hallway. Turn right underwater, then right again. Cross the room with the rubble and steel girders lying in the water, then cross the room with the shipping crates lying in the water and leave it through the underwater doorway with the stairs. Destroy the wooden boards on the doorway and then enter the doorway opposite the door you just came through. The Pulse Rifle is on a shelf on the left side of the room, together with an infinite ammo crate and an infinite grenade crate.

Red Weapon Chest
Enter STAG BUNKER and follow the hallway. Turn right and enter the flooded hallway. Turn right underwater, then right again. In the room with the rubble and steel girders lying in the water, look up to find a hole in the ceiling. The red weapon chest stands on the rim of that hole.

Arrow Head One – A bunker hidden behind the waterfall in the southwestern part of the map.
325174

Coms Bunker – A small bunker which can only be unlucked as part of a quest.
Enter STORM DRAIN from BEACH HEAD. Move forward, turn left and then move toward the building behind the two horizontal pipes. Behind the building, theres and entrance with a symbol above it. Go through, turn left, move forward, then go right when the path splits up. There’s a hatch on the ground here, which will only open as part of a quest. Inside the bunker, you’ll find lots of goodies, including an infinite ammo crate and an infinite grenade crate.

Phantom Rifle – A railgun that can shoot through obstacles and enemies alike, with a scope that shows enemies, anomalies and artifacts through walls.
Find the entrance to ARROW HEAD ONE in the southwestern part of the map, behind the waterfall. Enter ARROW HEAD ONE, turn right and follow the hallway, turning left the first chance you get. The Phantom Rifle is on a table in this room.

Hint:
Here are the hints scattered around the zone (in no particular order):
LIGHTNING IN THE POWER SUPPLY
HAMMER IN LIVING ROOM
WOLF IN THE WOLF DEN
STAR HIGH IN THE WELL WATCHED SKY
COG IN THE WATER WHEEL
Solution:
Node-01 in THE DISH: a four-pronged star
Node-02 in CONDUIT: a lightning bolt
Node-03 in CISTERN: a cog
Node-04 in THE BOWELS: a hammer
Node-05 in WOLF BUNKER: a wolf’s head

Enter THE PINES from JUNCTION 06 and follow the train tracks until you come to a train bridge. Cross the bridge, turn right and look at the grass-covered outcrop overlooking the beach. Jump on that outcrop and you should see a red flower. Pick up that flower. The next time you get close to Crow, you’ll automatically hand over the flower, permanently unlocking Crow as a companion. It’s possible you need to first find the data cache in OGR 018 and put it in the data reader, but I don’t think that’s a required step.
By the way: For me, Crow reliably spawned in the S-shaped hallway right after entering ADMINISTRATION from CONDUIT. Just leave the area and re-enter it a bunch of times and Crow should spawn eventually.

You can find this map on the little information terminals scattered around the zone. While the map isn’t very detailed, it does show the approximate locations of many important areas such as bunkers and nodes.

This guide collects information I got from playing the game myself as well as contributions made by other players in the Steam discussions section. Thanks to anyone who ever posted information in the Steam discussions and helped their fellow players out!
