OxRox 1.1 was released on July 26, 2026. The main addition is two-player online co-op.
The existing caves can now be played with a partner. Movement, switches, enemies, and falling hazards all run in the shared simulation.
OxRox can run at up to 2× speed, so added input delay is very noticeable. We tested deterministic lockstep networking but rejected it after playtests with roughly 200 ms of forced delay.
The released implementation uses GGPO-style rollback over Steam Networking Sockets. Local movement is applied immediately; remote corrections are handled by restoring and resimulating game state.
Read why OxRox chose rollback netcode or play version 1.1 on Steam.
