Done, as well as a bunch of easier challenges

Trying to do the random upgrades challenge on co-op (the second account being an alt). It's hard as fuck, mostly because you need to reach insanium and because I spent too much time not knowing how to buy revives.

New zombie campaign done. It was first try luckily.

New spidertron challenge

Finally managed to clear all remaining story chapters on insane!

All remaining challenges completed and insanium on endless mode.

Story 1 insane in 3 hours. Many challenges cleared, and some failed stage 2 insane attempts.

Started up. Combat is kicking me in the ass but I'm enjoying it! Played a bit, got the hand of being patient with the bow challenge and cleared chapter 1 on hard.
