Games like Sker Ritual

Last verified: 2026-10-24

Sker Ritual is a round-based co-op horror FPS for up to four players. The twelve games below share documented elements such as zombie campaigns, wave defence or cooperative objectives. Not all are FPS games or round-based: the differences matter. This is an editorial comparison, not a playtest or sales ranking. Console availability and crossplay are not inferred from a Steam listing.

The twelve

Co-op counts are the ones we could re-check. Dead Island 2’s three-player online co-op is supported by Deep Silver’s FAQ; its older crossplay wording is not used here as a current all-platform guarantee. Dying Light 2’s two-to-four range is from Techland’s support page. The rest follow current Steam descriptions. Dates are Steam’s listed release labels, not necessarily each game’s first Early Access launch or first release on another platform. For Black Ops III, confirm that the chosen edition includes Zombies: the Multiplayer Starter Pack is not an equivalent purchase.
