Buy It For £3.74
To celebrate the newly-added clans and tournament functionality, Brink is now free to play on Steam until the end of the weekend. The promotion will be available until Sunday evening, and should be going live momentarily (give or take a few minutes for the Steam servers to catch up). We gave Brink 7/10 in both our PC and console reviews: it's a solid team shooter, but doesn't quite deliver on its overly ambitious mission statement. Since it's free to play, however, you don't have to take my word for it.
You'll also be able to buy it for £3.74 while the offer lasts, which is heinously cheap. Be aware that the player base may well drop off once Monday rolls around - and the Agents Of Change DLC is not included.
Sadly, I'm not entirely convinced that the clans and tournament features will make much difference in the long run. Too little, far too late methinks. This should have been implemented months ago.
