They are from Resident Evil, the others are from Silent Hill. I thought the color depth nuking and shrinking would kind of make them all blend together...I agree they stand out a bit, but it could be worse.
(The Colt SAA is also from RE, BTW, but after I heavily edited it, it blends in so well you could barely tell.)
Thanks for the crits guys.
My favorite is the baseball bat since that's the one I did the most hacking on. The 'HPL' on the side was actually the idea of Marcus, a G&D admin from the old GW forums, who did the initial writeups/weapon sprites for Backstage 2 back in '05 or something. The game has changed a lot since then.
