4 Worth the pennies. Co-op with a mate is great fun.TheIndigoSwagger | 07/03/2008 | See all TheIndigoSwagger's reviews (1)So AO2 worth it? Well theres been hype and with such hype comes inevitable high expectations and in a nut shell despite not being without its snags and odd frustrating moments its a heck of a lot of fun. Kicked straight into online co-op mode with a mate and pretty soon we had mastered the controls after a brief and to the point training mission and racking up the cash in the main missions celebrating each dollar with in game character celebrations including high 5's and air guitar! So it was easy to get into but most important, gameplay and controls. The control system can be picked up pretty fast and players of GoW will be familiar with the style of play but where as Ao2 is maybe not as immersive as GoW it is certainly fun to play. At heart its basic, kill enemies get cash achieve objectives get more cash but with this money you get to "pimp out" and buy new equipment from weapons to body armor resulting in you wanting to get that extra kill and earn more than your buddy so you can show off your new gold plated ak47. Theres a good range of new weapons and upgrades to buy allowing you and your mate to choose different classes one could go down a more support weapon path while the other up close. The controls aren't as smooth as GoW or without the odd moments of frustration but the buddy abilities add an extra dimension to the gameplay that makes up for this. The agro system works well allowing one player to draw fire while the other sneaks round and makes the kills and is vital to achieving success. While at times it can be simply a case of hiding behind cover for X amount of time repeatidly gunning down wave upon wave of bad guys with some thought you can come up with more stylish ways to achieve the goal. Graphics are fine for what the games trying to achieve although theres not much in the way of destructable enviroment.In a nut shell, a lot of fun in multiplayer with enough upgrades and online modes to keep it intresting. Probably not half as much fun in single player so if your not on xbox live def rent rather than buy.Hope this has been some help its a bit late as im typing this up but think it highlights the main points about the game and helps you spend that hard earned cash on somthing you'll enjoy rather than regret.
