This is custom code that SIMULATES the AC130 smoke strike call like MW3 survival. It isn't a multiplayer killstreak like the mw2 and mw3 ac130. It's like mw3 survival and it's only for singleplayer.
campaign missions with specific objectives, more enemies, limited ammo, special ammo types, anti-air missiles, and a killstreak/combo counter. These are plans on my roadmap and may not necessarily all be included in the final game that will open the game up to more than the Infinite Respawn...
