Reach 1000 Updates in a Single Game

Reach 200 Homicides in a Single Game

Reach 230 Homicides in a Single Game

Have a Fighter Reach -50% Sanity

You’ll have to do something for these

Kill 100 Fighters with Landmines in a Single Game

Kill 200 Fighters with Landmines in a Single Game

To get these you will have to manually place landmines under your fighters. According to numerous posts on the discussions page this achievement is quite buggy and even after killing the fighters with mines it might not pop up. This took me 20 minutes and I (thank god) got it on my second try.

Have a Single Game last 7 days.

Have a Single Game last 10 Days

The absolutely easiest way to get these two is to start a quick game, select 4 players and after they die instead of pressing enter press space. This will unpause the timer and even though nobody is alive anymore the game still counts the time. This takes about 10 minutes.
