Just thought I'd pimp a mod that I've had some involement with.
Some of you may have heard of Action Quake 2. One of the most popular mods for q2. The devolopement team as evolved to produce Acition HL and now AUT.
It's not just another realism mod. Take a look at the site and you can get the details.
I played it and I found it to be lots of fun. Great release for an alpha. Very promising.
Check it out!
