New Maps and Weapons for U4 Multiplayer
You can probably make a new map like the fortress and The Monastery from U1, Borneo, Nepal, the Monastery, and Shambala maps from U2, London Underground, France, The Fortress(museum), The boat yard, Cruise ship, The Ghost Town, Sandstorm, and Iram Of The Pillars from U3. Now for weapons. The PO8-9mm(U2) MP40(U1+2) Tau-sniper(U3) KAL-7(U3) 9S2F-9mm(maybe spelled right)(U1+2) M9(U3) Mag-7(U3) G-MAL(U3) Dragon Sniper(U1+2) T-Bolt Sniper(U3) PM-9mm(U1) and the Arm Micro(U3). All of these for future multiplayer DLC. Yet to get mysticals. Maybe Cloak of Rabai(invisibility) or Curse of Shiva(splash, lasting effect, opponents are weakened, punching, explosive and gun damage) That is all! Have fun looking at my suggestions!
