RE3 Raccon City goes Left 4 Dead-ing
Here's a very good example of what you can do with the creation tools provided to you by Valve for their action-packed zombie-killing Left 4 Dead (Xbox 360, PC): recreate Resident Evil 3's Raccoon City.
It's very impressive actually, with the mod author Outatime obviously taking painstaking efforts to put in faithful details. Frame rate's admittedly dodgy, but nothing all too unforgivable. After all, this is only the beta 0.1 version.
