Have tons of games thanks to various bundles, but don't play them much due to time constraints :/. A bit more active on Steam.
Seems like somebody would need to make some Maps or gametypes/SP Mod to utilize this well. 8)
I haven't played it to make a judgement yet, though this gametype may make more sense (To hold a point for 8 seconds) if you have to literally hold a Dom point for a few seconds to gain it for your team a la Call of Duty. Perhaps that is part of the challenge. But it would be nice if game rules can be changed (again, this comment is based off not playing the mod yet!)
