- You must be playing on Tier 1 or higher to obtain this Relic.
- You need to get to Round 40+
- You need to progress the Main Easter Egg up till the point where you can teleport to Mars.
- On Mars there is a big circular platform in the middle of the arena. You need to get a certan number of explosive kills with C4 on the circular platform.
- It's only confirmed that C4's work for this (Unsure if it's explosive damage in general or not. Hasn't been tested from my knowledge)
- (Also unsure exactly how many explosive kills you need. One big hordes worth of zombies seems to be enough)
