Essentially a browser-based creepless/laneless tactical MOBA based on a modern mercenary theme. It has cover, AOO, and elevation advantage, however... along with a vast array of customizations. Gameplay is extremely skill-based of course, moreso since there are no creeps or lanes. There is some fun here, but mainly if you've got a good squad. ymmv
It's in CB but again, easy to get a key. This I believe is the best browser-based moba I've played (granted I havent play many).
