The Ultimate Strategy to Defeat the Z-Rex Solo
Alright survivors, after spending HOURS stuck on the bo6 bot lobby Z-Rex boss fight in Black Ops 6 Zombies, I finally nailed a solo strategy that works consistently. Here’s the breakdown:
Gear Up: Before even triggering the Z-Rex encounter, make sure you’re fully loaded. Best weapons IMO are the Tesla Arc (Pack-a-Punched to tier 3) and the Inferno Shotgun for quick DPS bursts. Also, Speed Cola and Jugger-Nog are 100% mandatory. Quick Revive helps too, obviously.
Phases: Z-Rex has three phases.
Phase 1: He’s mostly slow, just pepper him with shots. Watch for the acid breath and tail swipe. Keep moving in circles around the arena.
Phase 2: He gets aggressive and spawns minions (the undead raptors). Drop a monkey bomb immediately to clear them while you stay focused on Z-Rex’s weak points — glowing areas on his ribs and eyes.
Phase 3: He goes berserk — earthquakes, meteor storms, the whole deal. Use the environmental traps (especially the lightning rods!) to deal massive damage without wasting ammo.
Extra Tips:
Shoot his feet when he charges. It actually staggers him for a second.
Save your Wonder Weapon ammo for Phase 3 only.
If you're playing solo, the Z-Rex has slightly less health, but the mechanics stay brutal, so no slacking.
Took me 12 tries to beat him alone, but now it’s actually FUN once you figure out the rhythm. Hope this helps someone before they rage-quit like I almost did lol.
Anyone else find a different solo tactic that bo6 bot lobbies works better??
