4:LOOP is a third-person co-op shooter listed on Steam with a “Coming soon” release status and no confirmed launch date. The project is developed by Bad Robot Games LLC and published by PlayStation Publishing LLC, according to the official store page.
The game is set in a scenario where an alien invasion has resulted in large-scale destruction of Earth. A mothership is positioned above the planet, and the remaining human population is described as largely eliminated or transformed. Players assume the role of one of four survivors who are identified as immune to the initial event and are tasked with resisting the ongoing invasion.
The title is structured around a four-player cooperative gameplay model. Missions are presented as repeatable runs, with progression tied to repeated attempts rather than single-session completion. The store page describes a loop-based system where player death is an expected mechanic, with progression continuing across multiple runs.

A revival system referred to as “reprinting” allows eliminated players to re-enter active gameplay. The mechanic is integrated into cooperative sessions, enabling teams to continue missions after player elimination. The gameplay structure emphasizes repeated cycles, with incremental progression and persistent elements across sessions.
The store page indicates support for online co-op and cross-platform multiplayer. No additional technical specifications, pricing details, or release timeframe beyond “Coming soon” are provided.
