Shield Gun

The Shield Gun is only present in UT2004, replacing the Impact Hammer. Apparently it didn't do a good enough job, because the Impact Hammer returned in Unreal Tournament 3.

''The Kemphler DD280 Riot Control Device has the ability to resist and reflect incoming projectiles and energy beams. The plasma wave inflicts massive damage, rupturing tissue, pulverizing organs and flooding the bloodstream with dangerous gas bubbles. This weapon may be intended for combat at close range, but when wielded properly should be considered as dangerous as any other armament in your arsenal.''
