Basically, just make them similar in style to existing ones, but bigger.
I'd prefer 128x for rocket/grenade launchers, 96x for shotguns, and 48x for rifles/pistols, but feel free to use other size if you need. If you can provide it as an SVG (to be rendered at different resolutions) it would be greatly appreciated, but is not required to do so.
Please note that crosshair textures are needed, not the guns themselves (though I'd also appreciate some more pixelated textures for the guns).
Thanks in advance.
Edit: Additionally, if possible, the texture should be visible under any circumstance, so it should contain contrasting colors (like black+white). I'm asking too much
