FYI MirageOTS is based on (Ustrike/Shadow/Babek) server which I've released in here.
I got many requests asking for such old server and since I still have it on my PC and not going to use it at all so I decided to release it here, Hope someone can rework/update and benefit of it as much as possible. It doesn't contain any source/engine but it used old XML source/engine...
otland.net
and AFAIK only the owner of OxygenOT has the first/original version of it (Because he added few custom respawns/quests/items to the server I linked above and renamed it to Mirage) unless he sold it or shared it with someone else, So don't get scammed.
It is also the same server being hosted now as 8.60 (OxygenOT) with some changes.
