Sci-fi, Zombies, Industrial and Military is what comes to mind when viewing this nice set of mostly 16x16 and some 12x12 icons

I reached the end of tags, so I'll add the rest here:

speed, ranking, mouth, eye, laser, target, knife, armor, pill, shield, meteor, nova, cog wheel, flag, death, dead

Changes: compressed both images to fit other dimensions

Slightly changed version of http://opengameart.org/content/pistol-33x30 to have more common dimensions

Just a quick pistol I created as a placeholder for a game I am working on. Feel free to do what you like with it. :)

Shotgun sounds I got from soundbible under cc by 3.0

Made with MyPaint. 

These textures were originally created for UFO:AI, they are based off the work of Lukas "Rastaman" Beyeler who released his textures under GPL2 as I am doing. The original skins and the models they are for are available from the UFO:AI project under GPL2 licencing.

All the .md2 model files and the original source textures are here:

This Weapon pack is designed to work with this armor Pack:

Two pistols. One with a silencer and one just normal.

use these in your awesome spy games!

No credit necessary.

This is a collection of relatively low-poly firearms.  The iron sites are fairly detailed and line up appropriately for realistic applications.  The bolts / slides for most weapons are also animated.

It has the following:

• AK-47
• M4 / AR-15
• Dragunov (SVD)
• G3A3
• L85A1
• Mosin Nagant 91/30
• M1911

These do not have UV textures, only Blender materials.

One shot of each weapon, rifle and shotgun include reload.
