Can I play cooperative or CTF (Capture the Flag) SiN?
SiN doesn’t officialy support cooperative play because of the ABO system and other things, but due to code left over from Quake 2, it is possible. To play cooperative, you must run SiN, pull down the console (`, the key next to the 1), and type “set coop 1” (no quotes). Now you must type in the bsp name of the level. For an overview of all the level names, go here . There is a SiN CTF mod in the works, from the folks doing Cops and Robbers Mod for SiN. Check out Cops and Robbers for more info on when it will be released. Target date is February 1999.
