The latest instalment in the Red Faction series switches to a third-person perspective for one reason: carnage.

Buildings can now be reduced to rubble using anything from sledgehammers to rocket launchers, and it's this which keeps you hooked when variety deserts you.

The vehicles, for instance, are underwhelming, thanks to poor handling and repetitive, lengthy GTA-style drive-bys. The story is a paper-thin excuse for the main objective: to free Mars from its occupiers. It's explosive stuff though, with plenty of missions and side quests, and a strong multiplayer component when the single player campaign is done. Guerrilla is brash, brainless fun for those who thought Transformers 2 was a tad understated.
