Meh, get the stargate map, or the one of diehard (what I don't know ehere is), or download Lion(LS) Stargate Talisman special edition, but don't download that **** what xtc posted as it is really a poor noobish hack of a game with stolen stuff etc.

Btw there is abydos planet later in game too...........
Note that Stargate talisman SE is a reedition of the original version, first there was stargate public beta in 2003, then Stargate final in 2004 and SE in 2005. All of them differ btw.
The SE version was meant to be better, but becaue Lion made that in short timel time he didn't include glock and some things even some maps he planned to readd and the mp5 is just a minigun hack with I guess model from TO. But the other stuff is original mainly.
However there was no time left for the coop testing by me (which I originally planned while he was making it), at coop the episode has bugs.
It has own gametype and croshair too btw.
Also it is in czech language only, yet.............
Btw the beta version had english signs in base and voices etc, but he later made the czech ones for czech players.
