PvP and Multiplayer in Catch a Brainrot - The Player Interaction Menu Explained
Catch a Brainrot has a dedicated player-to-player menu, separate from the catch-and-battle loop against wild brainrots and Trainers. Clicking another player's avatar on the map opens a compact three-button interface - PvP, Trade and Exit - alongside their Roblox avatar, username and level, plus a preview of their equipped brainrot team.
PvP status: live
The PvP button is active and clickable in the player-interaction menu as of 2026-07-12, and PvP also appears as a selectable tab in the main menu.
Brainrots are leveled to the same level in PvP, so moveset choice and team composition matter more than bringing your highest-level brainrot. Full PvP modes, matchmaking and rewards aren't published yet; this guide will update as those details land.
Trading status: UI-only, not yet functional
The Trade button is visible in the same player-interaction menu as PvP, but the trade action does not currently complete.
A walkthrough published shortly after launch describes a full trade flow (map to player-click to Trade to picking brainrots to accept) - that appears to describe the intended feature as designed rather than a currently working trade. Treat trading as visible-but-disabled until this page is updated. No timeline for launch has been published.
The 6-slot brainrot inventory
The player-interaction menu shows the other player's brainrot inventory as a 6-slot grid - a limited, equipped selection, not their entire storage. Since PvP levels brainrots to parity, moveset and team composition in those 6 slots matter more than raw levels.
