Here's some work on brightmaps and sprites of Reavers faction.
Reavers are ex-military, now infected and with faulty implants. They are going to be the main anti-faction on lower levels together with mutants.
Their primary weapons are laser/energy.
Sergeant sprite - fully by me.
Commando sprite - taken from Realm667, with my adjustments, alt deaths and brightmaps (name "Devastator")
