0, so yeah, too many. I think if the barrel texture were more like an actual paintball prop (covered top to bottom in paintball spray from years of abuse) and had a surface specific sound then I wouldn't find it so out of place in most maps. The crates in my map will probably be replaced by cardboard boxes as soon as I make a texture I like, and as for 'new objects to hide behind for cover' - I don't think you'll have to worry about that wallpainter08, and thanks for your feedback.
Edit, I fixed the white outlines on the textures.
