I've been looking forward to this game, but I had expected a lot more.
/complain
1. Lack of weapon variety; I'd really like more of them.
2. No server browser.
*You can get a server browser by using the developer console.
3. Lack to filter modified games.
5. Repetitive gameplay, even with the AID.
6. Two maps in Versus... I find it really annoying how Valve depends on the Source SDK release so that users and modify their own maps and weapons. Versus is extremely fun but I am annoyed how people usually leave when they become the survivors because they always want to play as the infected.
7. noobs that hit you in the back with a shotgun, people that boss the whole team around and won't shut up
(teamwork people), people that stray away from the group and die... then I try to go rescue them and die, people that just don't help, and people that screw around with the witch when they don't need to.
I'm hoping the gaming community will help fix these things with modifications like they did to CS:S, TF2, and HL2.
(except for #7)
It's still a fun game, it could be better though... I also got a cool new Zoey skin
here.
