About Project Horizon

✦ AI summary

Project Horizon is a chaotic cooperative space combat game where your up-to-4-person crew must dynamically manage guns, flying, radar, and reactor maintenance while constantly racing to repair battle damage across your ship. What sets it apart is its emergent damage system—instead of health bars, specific compartments leak air and break down realistically, forcing your crew to make tough tactical decisions about what to prioritize fixing mid-combat.

Players will be members of an up to 4 person crew. There are no assigned roles, so you'll have to communicate among the chaos and decide who will be:

Manning the Guns
Flying the Ship
Operating the Radar and Auto-Turrets
Preventing the Reactor from Melting Down

However, EVERYONE will be repairing the ship constantly as it takes damage throughout combat. When your ship takes a missile to the aft compartment, there is no health bar slider that gets a bit lower. Instead, the aft compartment starts leaking air, perhaps the oxygen generator was stored there? It is up to you and your crew to decide what needs fixing first. Can your crew afford to take someone off of the guns to seal up the holes? Or perhaps you have plenty of oxygen stored up and sealing off the compartment is smarter for now.
