The game uses Solidshield with a 5 machine activation limit (no activations credited back over time as far as I can tell).
This is also on the Steam version so those who wanted to buy it on Steam (at the US price hopefully) hoping to avoid the DRM on retail copies are going to be out of luck.
What's worse is that there's no disclosure on EA's website or the Steam store page that this is the case. I had to find this info from other people who have the game. My only hope is that there's disclosure on the retail packaging (it'll be in fine print on the back of the case if it is there).
**** you EA/Crytek.
