There is also a major graphical glitch in the 'c2a4c' map (as a result of the 2013 update), rendering the game virtually unplayable unless the multi-core rendering setting is turned off.The crowbar makes a metal-on-metal striking sound even when hitting wooden objects.It is (rather infamously) possible to take down an Apache helicopter with a few Glock 17 rounds.The shading gives some weapons a plastic toy appearance.
Of course, it's possible to make maps for the game if you manage to configure it properly.
