Corssfire magnum is just derp in my opinion, metal cades are unnecessary, Hl2 smg maybe, although the chance of firing 2 shots doesn't look very good to me, but adding somehow nerfed para, ak47 and the windowmaker(aka css terrorist auto sniper which is already added in the zs game and can be obtained only by picking it up in a map) for a next kill upgrade like 75+ kills always seemed like a good idea to me.
