Build a fortress, defend your flag, and break into the enemy keep to capture theirs.
About KeepRaid
Each team builds its own keep before attacking the other one in KeepRaid, a multiplayer take on capture the flag. A match moves between building defenses, holding them against intruders, and tearing through enemy walls to reach the flag and carry it home.
The creator says it was inspired by King Arthur's Gold, a game they loved and miss. With Claude Code as the tool, it ranked 197th of 945 at Vibe Jam 2026. Matches are online, and the game plays in the browser.
Because the players shape the map, no two keeps have to look alike: your walls and layout are your defense, and the other team's structures are the obstacle you have to break. The whole match fits in three steps: build it, break it, take it.
