This is hands down exactly what I've been waiting for.
I started playing ARMA 2 and ARMA 2 OA in anticipation of Stalker SHOC SMP 2.5 which has been taking forever. I discovered ARMA 2 had more to offer than the original STALKER engine.
Then I found this mod and realized my dreams had come true. All that was missing was the addons that stalker SMP 2.4 had put on such as WW2 weapons and a decent progression from rookie to master stalker.
I tried to implement some of those featured into your mod using ACE and the DEGENRATION survival Zombie horror map I found.

I hope this maybe this gives some inspiration on where to take the mod next. As it stands it's phenomenal. If it gets any better, I'll never play anything else! Great work and I'm looking forward to the next release.
