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.

ROGUELITE PROGRESSION

• Unlock permanent skill tree upgrades.

• Return stronger.

• Break the game on purpose.

DISCOVER. MUTATE. REPEAT.

• New swarm species that changes playstyle.

• Rare items and exotic genes.

• Endless builds that change how your entire organism behaves.

• (WIP — more on the way.)

FINAL CHALLENGE: "Vanilla Mode"

• Reset Skill Tree & upgrades.

• Start from zero.

• Defeat the final boss in pure vanilla chaos.

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
