Suffering from success 2

Stage 2, where flamethrowers gives you an extra advantage against enemies in this cold environment.

I'm steadily maxing out on the levels of my weapons to get the rare achievements for this game, the hardest being killing a lot enemies using melee weapons since most of the time, barely any could get close unless the waves get to an extreme extent when you play the Endless variant of any of the 3 stages.

Truly, I am suffering from my own success.
