Unlocking the Bus Relic in BO7 Zombies Cursed Mode

Unlocking the Bus Relic in BO7 Zombies Cursed Mode is one of the most demanding Easter egg challenges currently available, and many players looking to save time even explore options like a buy bo7 bot lobby service to skip the grind and focus on the relic trial itself. The process requires careful preparation before loading into a match, precise execution during high rounds, and smart strategies once the special trial begins at Blackwater Lake. Mastering each phase ensures that the Bus Relic not only unlocks but becomes a reliable part of a late‑game build.

Before starting a run, the most important requirement is reaching Cursed Tier 2 so the Bus Relic trigger can appear in your game. Once that is done, you have flexibility in your overall setup, but the guide emphasizes building around Brain Rot damage with the right augments and relics. Recommended options include running Plague or Caustic Fumes as your major augment on Brain Rot, then pairing Explosive and Super Serum to significantly boost the killing power of turned zombies. Players are warned not to equip the pheromone augment because later steps rely on regular zombies naturally attacking elite enemies without being distracted.

The opening gameplay goal is simple but grueling: push all the way to round 60 in Cursed Mode. This is not optional; the entire Bus Relic sequence hinges on surviving to that milestone. For those who struggle with long runs, external high‑round strategies and routes can help optimize kills, manage resources, and maintain map control. The important part is to arrive at round 60 with a solid setup, strong weapons, and enough confidence to play perfectly during the critical round.

Once round 60 begins, the real test starts: you must complete the entire round without taking any damage from any source. This includes obvious threats like zombie hits and explosions, but also less obvious ones such as fall damage, trap damage, and potential self‑damage from powerful weapons like the ray gun. Even if some perks would normally negate the damage, the guide notes that certain self‑inflicted hits can still fail the condition, so caution is essential.

There are two main efficient methods to clear round 60 flawlessly. The first involves using the Timed Out Gobblegum: when you see the first zombie on round 60, activate it to instantly end the round with no damage taken. The second method relies on waiting for a Ravager round, then immediately activating the appropriate trap to wipe out the enemies in one go. Executing either approach correctly will satisfy the no‑damage requirement.

After successfully completing the round, an audio cue from Mr. Peak signals that the condition has been met. At that point, travel to Blackwater Lake near the boathouse to find a new portal that starts the Bus Relic trial. This trial revolves around killing zombies with other zombies, meaning Brain Rot will do all the work if positioned correctly. Tight spaces, chokepoints, and doorways help corral enemies so Brain Rot zombies can shred hordes and elites alike, including during the lengthy Zersa segment. When the trial is finally completed, the Bus Relic is awarded and can be enabled to make enemies regenerate health, dramatically changing the flow of future runs.
