Can you play against bots as one team ?
No, there are no bots for this mod.
The Manual link doesn't work and it wont run after the installer finished
The site has taken a bit of a hammering from spammers, but it's accessible again now.
The mod has come along way! Just wish it had more people playing :(
Suddenly an Anonymous guy.
Please tell me this thing runs on Mac.
I am not aware of anyone having run EX on a Mac. I am not even sure that the Source SDK Base is available on Mac. I think it unlikely due to the windows library references in the source code.
Valve might release a posix compatible SDK one day, but I would not hold my breath.
Well, If you ran it in a composed windows environment like Wineskin it should work in theory, if i have the time i'll test it out.
really enjoying this mod kinda wish it was more active,really fun while people are on tho thanks for the mod.
HL2 is NOT required to play this mod, just the "Source SDK 2007 Base" , which you can get from the Tools Library in Steam.
