How many GB is Brainrot Online?

2 GB

That is less than the typical Shooter game, which needs about 8 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Brainrot Online is a fast, chaotic, and absolutely unhinged multiplayer FPS where strange brainrot-inspired creatures clash in ridiculous battles. Join existing servers or create your own, jump into matches filled with real players or AI bots, and fight your way to the top across three unique maps designed for nonstop action.
