THIS GAME IS APPALLING - Please avoid if you take nothing else away from my review.
Single player - incomplete. I played a few missions (I think I stopped after the river mission) and that was more than enough. The story is very samey, seemingly impossible enemies and alot of restarting from checkpoints. I was outraged at the SPELLING ERRORS by the creators on some of the mission briefings... i.e Breakthrough through the base... WHAT THE HELL?! This might seem very picky but if you are going to charge me 30+ of my hard earned pounds on a game I want perfection, or as close as possible to it. Slow-mo kill cams were neat, until just over 50 of them have passed and you feel like half the time you've spent on this game is watching bullets fly through various objects on their way to their target. At one point on the first stealth mission I found a rather nice rock to crawl into and then proceed to run around underneath the map and shoot the AI (they could still see me through the top soil and tried shooting remarkably.)
Multiplayer - 3 hours. Again more than enough play time to establish that this really is the worst experience I have had. I would rather play viva pinata. Maybe even just sit at the dashboard and stare at the screen. Anything has to be better than sitting in a game tearing your hair out because all spawn points in the game are specific and are in clear line of sight from half the map. One shot kills apparently don't exist even though you've got more gun sway than strafe sniping on MW2 and a fascinating inability to hold your breath for more than 1.5 seconds. Pure unadulterated disappointment. No weapon mods as well was a very clever move by the developers... I loved it. The linear system just seems to work perfectly at preventing you from having any input into your kit - come on guys, this is 2010. At the very least let us add on a camouflage. The map system is atrocious, giving an overall guideline of where the enemy is, meaning that sneaking around like a real sniper does is out of the window.
Please don't buy this game and we can work together to make sure that this very small, unknown developer doesn't get the chance to have a second chance. And if you do buy it, when playing, please try and find 6 different AI faces... If you do then comment to me and let me know. I'm convinced that there were more faces on enemies in Goldeneye.
