Skip it if you…
Saves you a refund- Players seeking a long campaign may find seven scenarios too limited

- Players uninterested in creating or downloading community maps may get less value from the workshop content
Our take on OSES
The focus on switching survivors and managing their positions adds a tactical layer, but it also limits the game’s simplicity as a straightforward shooter. Attention must be divided between aiming, movement, ammunition, and group safety.
What is OSES?
OSES combines shooting with tactical survivor management in a post-apocalyptic setting.
Three characters use different firearms, and changing between them is central to keeping the group safe. Positioning affects objective completion, while ammunition must be managed during encounters. The game includes a seven-scenario campaign, 20 timed challenge maps, and four modes: escape, defense, food rush, and boss battles. Match credits can be spent on weapons, drone drops, and hats. Workshop support lets players make, share, and download maps. The creation tools cover three modes, allow mixed-mode designs, and support maps built around narrative elements.
