This next decision is based on the fact you chose, “Go After Deadeye Joe”, and now are coming up to the second main decision. You worked you way into the enemy’s base and it seems you have entered a trap. (Yes, this is pretty much the same way leading up, you just get different Endgame results) The traitorous doctor gives you two options to pick from
1. Fight to the end.
2. Surrender and fight later.
First thing you need to do is make a save at this point before you make a decision.
If you to pick, “Fight to the end”, this is going to prompt you for Ending C. No other decisions after this, simply and skillfully destroy everything, and receive the achievement.
If you to pick, “Surrender and fight later”, this is going to prompt you for Ending D. No other decisions after this, simply and skillfully destroy everything, and receive the achievement.
Do you remember I said to make a game save before you made your decision? Go ahead and load the save. Select the other option and complete the game for the other achievement.
