Test Tube Titans: Taster Trial is a multiplayer-focused variant of Test Tube Titans https://store.steampowered.com/app/1231540/Test_Tube_Titans/ .

VERSUS MODE

Wrestle your friends in 2-4 player local multiplayer. The perfect way to settle a dispute, prove your skills, or just unwind with a friend! (multiplayer requires a controller for each extra player)
Every time you play you'll get a brand new procedurally generated titan: no two titans are ever the same, and the same goes for every fight.

CREATIVE MODE

Dive into the creative mode to create yourself a custom titan from scratch. Give it new physical mutations and special abilities. Then take it out for a stroll through the neighbourhood to create as much damage as you possibly can!
A complex per-limb control system and a fully physics-based world make this an experience unlike anything you have played.
Hours of fun await you in Test Tube Titans: Taster Trial!
