A friend of mine recently acquired Left 4 Dead, the new zombie game from Valve software.  It meets our requirements of at least 2 player co-operative on split screen, and four player over Xbox live, the ability to work as a team to accomplish your goal, and the ability to screw over said team if the going gets rough.  It’s a first person shooter, which we are all most comfortable with, and it throws your characters in the middle of a zombie infestation with no back-story and no other objective except to survive from one point to another.   Which, if you think about it, would be what would really happen if you were to wind up in that situation.  No narrator is going to come over the loudspeaker and tell you what happened and what you should do next.
We set out on the first level and cranked the difficulty setting to max, because zombies aren’t easy.  It begins in an apartment building and you must make it through to a subway station with one safe-house full of ammo and health in-between. I would tell you more but we have yet to successfully make it past the subway.
As if Zombie hordes rushing you wasn’t enough the developers added some special “boss” zombies to the mix to spice thing up.  If we ever got a bit complacent after finishing off a zombie horde without losing much health, and lollygagged around looking for explosives a giant tongue would shoot out of a window and grab someone dragging them away.  The hardest moments were when you ran into the massive <a href=”http://screenshots.teamxbox.com/screen/81558/Left-4-Dead/”>tank</a> (basically a hulk sized zombie with forty times the health of the regular sized ones) zombie outside of the “boss” battle zone.  The are no clear spawn rules, the AI can put anything anywhere, which is half of the fun.
good stuff, until your teammate throws a molotov cocktail on you as you try to free yourself from a giant tongue, because he felt you were’t going to survive. Remember: don’t shoot teammates!
