so like i saw an advert for brink a few days ago and been watching some videos on youtube and on the brink website and stuff and it looks pretty sweet. but i have some questions about the online gamplay...

what kind of online match types do they have ? like deathmatch, CTF you know stuff like that.
do you have online ranks in which you can go up in levels and unlock different [censored]?
is there any sort of co-op gameplay?

Only online matches are objective based, Each map having it's own unique objective. This of course is doubled by 2 considering each side or faction has an opposing objective then the other.

You do get levels from 1-20 each level earning you an ability point to spend on boosting health, Getting turrets or any other class based boost you could want.

This game is made to revolve around co-op and multi-player. Anything you can do in Single Player you can do with friends or online with other people to make things interesting.

You do level up and gain perks, weapon upgrades, abilities, etc. However the game is all objective based. You do objectives and you progress through the level. The objectives are usually somewhat different and varied (within the level). You can campaign mode or challenge mode co-op, but the campaign mode with a friend is a glorified bot match. Just a heads up is all

What guys said.
