Jesus Killing Fields is hard as hell. For anybody that needs help with it this is what I did. I gathered supplies starting with the box you start near then ran counter clockwise to the southeast to gather supplies. Only set up mines at the very start at at the bottom near doors to distract them since mines are pretty much useless for later parts of the stage. After getting all the supplies I ran to the upper hallway since it was the easiest area to defend and set up multiple c4 blocks on both ends until they realized where I was. Just defend there until around 10 seconds when they start to really rush you and set off all the c4 when you can't gun them down fast enough. Even then I ran out of medkits at around 1 or 2 seconds left and barely won.
The rendering takes way too long. Should be a restart button instead of abortion button that automatically restarts the level since it has already rendered. The rendering lag was especially atrocious on level 24.
I can't proceed to the next floor because the floor entrance was created right next to a trap. I even tried creating a stone path on the other side and they just go back to the entrance. What a bunch of BS.
Probably already mentioned but for the hard badge DO NOT use the homing rockets. They're terrible and ignore close enemies just to seek out foot soldiers. It's better to get at least 4 homing rocket soldiers instead.
I suspect that the reason the second hard badge is a hard badge is due to having to beat Atropos. I don't even know how I did it considering he got me twice with the attached laser attack in the same battle.
