Overview
About this game
SWARM SURVIVORS
In GREX, you don’t play a hero — you command a living swarm.
Hundreds of Grexlings move, fight, and sacrifice themselves as one organism.
You do things no single character could ever pull off.
CONTROL THE UNCONTROLLABLE
Swarm AI Combat – Your Grexlings dodge, chase, collide, and intercept automatically.
Body as Weapon – Ram enemies, surround them, shred them, overwhelm them.
Mass Sacrifice & Rebirth – Lose dozens, rebuild instantly, and come back stronger.
Shape-Shifting – Use different shapes and formations to survive.
CRAFT YOUR PERFECT SWARM
Genes – Combine gene types to create unique Grexling behaviors.
Merging – Fuse genes into higher tiers for absurd power jumps.
Passive Items – Heavy bonuses with real trade-offs.
Upgrades – Level up, boost stats, and evolve your swarm’s instinct.
Digging – Tear through the arena floor to find healing and diamonds.

MUSIC, POWER, VFX
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
