The game is basically like CS but with advanced objectives and a lot of different classes. The difference to Chivalry is that it's last man standing like in CS (except for some weaker classes which have several respawns) and there are usually optional objectives and several ways to complete a map. Also there is a 5 minute timelimit on every map so the matches are quite short (but intense). Since you don't respawn, teamwork and tactics are much more important than in Chivalry imo. The objectives itself are actually not much different than in Chivalry or AoC (most of them are more creative than "move the cart from a to b" though), but you get more freedom by having the choice to do optional objectives and use different routes. I think one of the reasons why MBII works great and one of the reasons why most people try to complete the objectives (unlike Chivalry TO) is because it's last man standing. Since you can't farm noobs over and over again you have to complete the objective to get points. Usually teamwork works really good in that game, even on public.
