Looking forward too all the originals from Arkham Asylum, I mean many of the not major villains will have side missions in AC. Like the Bane and batman team up. And the Deadshot missions. They expand the depth of the batman universe without over stretching the plot. So as many as needed or all xD.
It is like Left 4 Dead, there are up too 4 player Co-op, and much like Borderlands you pick one of the 4 survivors each with there own skills. Then play the game and tag in friends or random people into your game world. Left 4 Dead this game isnt completely, it bears more resemblance to Fall Out with the RPG leveling elements and shooter play. Melee weapons are focused on but guns are available in limited numbers. If your expecting to run in gun this game isnt for you, this game is about picking your targets and avoiding what you can and dealing with what you have to. Its a great Zombie adventure but a left 4 dead it isnt entirely, keep that in mind and shop smart ;D
splinter cell conviction is a 360 exclusive, the ps2 games are available, while HD remakes of the splinter cell series is close to coming out. Id strongly recommend MGS, there series as a hole is a great story line with stealth aspects at their best. Sometimes considered the founders of the stealth genera.
if you preorder from best buy you get the robin character, so far they havnt said finite things for every game retailer. Here are some places with their preorder bonus, look for "Country: USA" http://arkhamcity.co.uk/viewtopic.php?f=4&t=2751
I say left 4 dead, you cant beat the founders like Resident Evil. But L4D gave you partners and still at times you could be f'd by the hordes. It took the slow marching zombies of yesteryear, and turned them into intelligent creatures of the earth. Possessing the ability to navigate seamlessly while pursing you, and if you arnt careful, will quickly overwhelm you. While the general mass of zombies are annoyances, the special infected are designed to stop the common flaws of player error, camping (Charger Spitter & Smoker) while the lone ventures will face other threats (Hunter Jockey & smoker). It made a balanced and still sometimes difficult adventure making though the locations. I feel it makes a old genera new again with gameplay that doesnt seem to tire itself out. Each of the 5 campaigns can still feel so different after dozens of plays.
