When you have nightmares does a certain Presidents daughter's voice pierce your sleep?
"LEON!!! HELP ME LEON!!!"

And thus Resident Evil 5 picks up. Many fans wondered whether the T-virus would make a reappearance, or whether the Las Plagas would haunt another portion of the world. Long story short: It's kinda the Plagas. Chris Redfield is sent to Africa on a mission to capture a man who is suspected of selling Biological Weapons on the black market, and thus, once again, all hell breaks loose.
Okay, enough backstory. Check it. In RE5 you get to play the entire game with a partner, whether it be with CapCom's self-proclaimed smartest AI, who appearently finds it effective to shoot enemies THROUGH it's human partner, or with a friend on the same XBox, or over XBox Live. Go CapCom for trying something new, sort of. The new partner system is insane when you play it over Xbox Live. Each partner retains there own inventory, gold stash, ammunition etc. Ammo and Herbs can be trades and given to the other player, guns however, cannot be given. Which makes sense, even though it is annoying. When two human players are playing the game, one can be the point man, armed with a shotgun, pistol,

Off of this whole two player thing. The game runs very well. Control system is much like the previous games. TONS of bonus material. Myself, I am only 23% through the game.
Mercenaries Mode: Dude. I always loved this mode. I still played this mode on my Wii when I came home for the weekends. It's just amazing. Go kill stuff, you have 2 minutes. Go. That's just awesome. I would like to think of my partner and I at being pretty good at this game. Yea, not. We played one round of mercenaries, and they graded us with a D. The lowest rank next to death. Damn. Lots of practice ahead of us.
Overall
Graphics: 9/10 - Beautifully terrifying graphics. Recommendation: Diaper.
Sound: 8/10 - Well done.
Gameplay: 9/10 - Same ole high quality I expect from the Resident Evil team.
Difficulty: 8/10 - The game is pretty difficult the first time around. After the first playthrough it is easier, with the option of unlimited ammo, the game just gets easier. The mercenaries mode is where the difficulty really shines. You have 2 minutes. Kill as many things as you can. O yeah. You get the guns CapCom lets you have. No uber shotgun here... Damn.
Replay Value: 9/10 - The main storyline can be replayed using the SAME WEAPONS you just upgraded throughout the entire previous playthrough. Nothing like killing first level Manjini with a fully upgraded shotgun. The Mercenaries mode is crazy hard, that is where the real challenge of the game lies.
Multiplayer: 9.5/10 - Amazing Multiplayer abilities. There is nothing more terrifying than hearing your partner scream because of something, and you have NO IDEA what is causing it. So you scream anyway.
Overall Grade: A-
Recomendation: Go Buy It. Seriously. You won't regret it. Just make sure you have a friend who has it also and is willing to play it with you.
