basically sp mod but in a server and without the ability to keep replaying(as i imagine that'll create many bugs).
why should this exist?: well, the population of the game became quite low and it's harder and harder to find someone to play with in non-competetive mods so this can 1-help people kill time until someone joined their server. and 2- let people watch someone playing alone,. 3-some people may prefer to play at their own pace but still hangout with others in a server.
