HaZardModding released the first version of its co-op mod for SiN Reloaded on November 12. It lets up to four players tackle parts of Ritual's 1998 shooter together, with the bank, construction site and subway among the areas covered so far.

Chrissstrahl and the HaZardModding team built it around level scripts. It leaves the game's executables and DLLs alone. The team is focusing on the main campaign, and this first download covers the early levels listed in the release notes.
