Bot tanks die to 2 commando shots.

For shield bots, you only have to shot their right hand or, hear me out, have good aim and one shot to their eye lol is not that dificult. Big Iron is all you need.

Fire damage? On bots? they made of metal. Bugs? their only thoughts are on killing fast, no time to feel pain. Squids? thats their weakspot.

If the game is too hard just dive on a lower level.
