No matter how much I hate EA...I can't deny I fucking LOVE the Army of Two series, the new one
Army of Two: The Devils Cartel is beyond awesome.
Yes it is expensive (£60 on PSN) but, luckily a friend of mine bought a hard copy, and we borrowed it to complete the story mode
Although, if he had bought on PSN, we would have just done what we do with everything else...login to the other persons account, download it, and enjoy playing it
Done it with a few games on PSN now, including DRM for games (More recently, the Revolution pack for Black Ops 2) - Split the cost, share across PS3s.
