First let me tell you what is missing from this game.
Mercenary mode, 180 turn around button ( It annoying that you can't really turn around fast ), weapon customisation ( its VERY dark game that you're not allowed to add a simple FLASH LIGHT to your gun ) not a lot of hand guns, weapons really feels bad ( recoil and aiming ), you will usually see people playing with Advance SMG or Hammer sometimes Juggernaut ( USAS shotgun ) because they are the most effective in a game. This game lags and glitches really badly sometimes you are well away from another player only to be grabbed and killed seconds later... It seems players "see" differently. Campaign 7 missions... 3-4 h of gameplay. Even on Veteran there are missions you can just Rush in.
Another thing missing Puzzles and Interesting Boss Fights. Seriously it comes down to one thing : Shoot it. And there is way too much ammo. You will never need ammo. Boxes are to be found everywhere lol... Npc acts really dumb and don't expect much help from them. You can't really interact with environment ( pull levers so your teammate can cross over bridge ) This game is missing SO MUCH. Its not even scary. Multiplayer is just one big frustration if you can't get Assault class or Medic class then you will die a lot. Hero mode is just like Team deathmatch but characters are Beefed up... ( really hard to kill 2-3 clips or 20 knifes... lol ).
In theory it was a good idea but in the end its not worth it. Wait for the price to drop.
Now the good points, Veteran difficulty offers friendly fire lol... Classes are balanced ( except fro Spectre that doesn't do anything in campaign mode ) but multiplayer is unbalanced as hell... It's somehow fun to play even though there is so many flaws and fail ideas... don't know how to put it... but it's just fun to play 4 player co-op seeing them getting infected but then... you start to shoot sniper rife and you realize that it takes 2-3 headshots to kill military guys... sniper rifles are seriously under powered... Switching to side arm is just frustrating and boss fights are boring. It would be more fun if there were some tactics but no... just shoot it where it hurts. Thats it.
Resident Evil ORC is a hollow child from a Capcom ( shame on you ) family. It frustrate you and at the same time give you some fun. Its not worth 30-40 pounds for a glitched game and campaign that is way too short.... even some indie games offers longer campaigns LOL. Fin ~~
