In GREX, you don’t play a hero — you command a living swarm.

GREX is powered by a thumping trance-techno soundtrack and glowy neon VFX — swirling trails, pulsing lights, and particle storms that turn your swarm into a cosmic supernova.
GREX blends bullet-heaven chaos with deep buildcraft - but the star is your swarm.
Learn it. Shape it. Weaponize it.
Can you control the chaos you create?
Have fun Swarming,
Mike
