Well, I don't know if you're still around to look at this feedback, but I'll give it anyway. I put it up on the beta server, and it's kind of amusing.
- The flags are impossible to get. People just sit on the elevator most of the time (and they're almost always the last to die).
- Barricades should stay up longer - like 10-15 seconds. Possibly add larger triggers for them as well.
- Spawns are facing to the side. Not sure if that's bad - basically the first person to turn 90 degrees and shoot gets kills. Maybe add permanent cover for the spawn areas (though if the barricades stayed up long enough, they could be up from the previous round).
- It's possible to get stuck (see demo).
- Some spawners give you loaded co2, others don't. I kind of like the ones that don't, because it forces you to change tactics while you reload. I'd make them all consistent, though.
- I'd move the low position of the barricades (lip setting, I think) up a bit, so the top edge of them doesn't sink into the ground.
I've attached a couple demos - one is just to give feedback, and one is actually playing on the beta server. PM me if you need the login for the beta server to play test.
