Petri Party is a physics-driven party platformer that blends action and casual elements into fast-paced local multiplayer sessions on PC. Players control disposable slime prototypes in a laboratory micro-world, relying on momentum-based grappling, wall-walking, and ceiling traversal to navigate arenas and eliminate opponents in one-hit kill rounds.
Gameplay
The core loop centers on high-skill movement and precise timing. Slimes swing from surfaces, chain grapples for speed, and recover from near-misses with well-timed hooks. Every arena surface becomes part of the battlefield, including moving platforms, portals, transport pipes, and launch pads that enable attacks from unexpected angles. Weapons from different technological eras add variety, each with distinct throw, recall, launch, or fire mechanics that reward quick adaptation during matches.
Local play supports up to 18 participants on one machine, while Steam Remote Play Together allows up to four additional players without requiring extra copies. An interactive laboratory lobby lets groups test weapons, switches, pipes, and teleporters ahead of rounds. One-hit kills maintain short, tense matches that suit repeated play sessions.
Game Modes
Classic options include Deathmatch and Team Deathmatch for straightforward elimination. Murderball emphasizes ball control, Hot Potato requires dodging a timer, Golden Gun focuses on a single loaded weapon, Waypoint Race challenges players through grapple-based courses, and Slimeball delivers chaotic basketball-style scoring.
Stackable modifiers alter each round. Examples include low gravity for altered movement, ricocheting bullets that bounce off walls, oversized projectiles, reduced lighting that forces reliance on muzzle flashes, or fully random modifier selection. These combine freely to create varied experiences across the more than 50 handcrafted deathmatch arenas.
Co-op Campaign
A dedicated co-op campaign places teams inside Helix Ward-9, a research facility filled with progression elements. Players collect keycards, unlock weapons through play, and advance toward an exit while uncovering limited story details. The mode preserves the same chaotic local co-op focus as the party rounds, with secrets hidden throughout the environment.
Is It Worth Playing?
Petri Party targets groups seeking couch co-op chaos and quick, high-stakes rounds built around movement mastery and weapon experimentation. Its emphasis on local multiplayer for large gatherings, combined with remote play options and a focused campaign, suits players who enjoy party platformers with physics emphasis. The game remains in a coming-soon state with no released player reviews available yet, so potential buyers should monitor updates from the developer for final release details and any post-launch support.
