A review site gave it a 4/5 with the only complaint that there was no single player. Otherwise, they said that the online play was amazing and it has some of the best PS3 graphics.

Also, the reviewer that gave it a 6.5/10 once worked for OXM.

Otherwise, a must own PS3 title.

Could this mean PS3 Multi-player demo of Haze is announced?
"Free Radical's Derek Littlewood: We've been discussing multi-player beta, it may just end up being multi-player demo, but we are looking to do a pre-release, a playable version of the multi-player."
