Co-Op Z-Rex Fight — Communication Is Everything
Yo! If you're trying to beat the Z-Rex in bo6 bot lobby Zombies with a squad, LISTEN UP — it’s way different than solo. It’s not just about firepower, it’s about communication and timing.
Team Setup:
One heavy DPS (LMG or explosive build).
One Wonder Weapon specialist (ideally with the Frostbite Cannon).
One support (healer field upgrade + monkey bombs).
One "trap runner" (someone who triggers environmental hazards while dodging).
Biggest Mistakes We Made Early On:
Not calling out when Z-Rex was about to roar (stun move).
Overlapping monkey bombs and wasting them.
Everyone standing too close together = one meteor = team wipe.
Pro Tips:
Assign zones. Everyone covers a slice of the arena, so you're not all scrambling.
Mic check. Someone has to call out the acid pools, meteors, and minion spawns.
Rotate traps. Don’t burn all the lightning rods early — save them for Phase 3.
Ultimates stagger him. If you all pop your field upgrades at the same time during the final charge phase, you can stun-lock him briefly.
Our best run was 17 minutes from spawn to Z-Rex kill with only 1 down. Absolute CHAOS but so satisfying when everyone’s locked in.
Also — whoever’s running monkey bombs, PLEASE don’t throw one unless absolutely needed. Saving them for the minion flood in Phase 2 is literally the difference between winning and getting chomped.
Anybody got builds you swear by for co-op? Especially curious what Field Upgrade combos work best bo6 bot lobbies together.
