Killing Floor: Voltage and Magma DLC Characters!

Foster and Skully's alter-egos take center stage here, all lit up in neon!

• DJ Skully makes a new appearance as DJ Voltage, sporting a blinding neon-blue skin!
• Mr Foster joins the party as Mr Magma, in a blazing red suit!

Both characters come with their own particle effects - in neon, naturally!
