Co-Optimus reader roland sent us a tip about the PC version of Valve's 4 player co-op zombie shooter Left 4 Dead.  In fact, we almost missed the tip because we are all so busy knee deep in zombie guts.  It appears, at least at some point, the PC version of Left 4 Dead will support the same split screen option has the Xbox 360 counterpart.  In fact, it's already there - just disabled.

How you ask can that possibly work?  Two keyboards and mice?  Well, not exactly.  The "ideal" situation, according to a Valve employee on the official forums, is to have two gamepads, much like the 360.   Of course, a keyboard and a gamepad would also work just fine.  

According to the post they are looking to re-enable the feature as some sort of unsupported bonus feature shortly after launching the full product, which was a few days ago.  This is definitely awesome news, and hopefully something that's the start of a growing trend!

They've reenabled it, because I've been playing it with my lil. bro in the Demo, then they disabled it. Now they put it back in, but without a command that allows you to go on the Net with SplitScreen enabled.
So I can play with my bro (and with 2 idiotic bots, dunno why they are so idiot in my game :\), but I can't play SplitScreen on the Net (in the demo I could). I hope they turn THAT feature back on (it's just a simple console command, c'mon!)

Your bots are dumb? Mine are amazing. They never friendly fire, and they always kill zombies effectively and never run out of ammo.
