The same as Black ops itself. Treyarch+Activision.
The game was made by Treyarch and not Infinity Ward who makes Modern Warfare. The made 3 Map Packs and now are making new ones for the latest game Black Ops
yes. You have to Buy the Map Packs to get them and they will not play without the game. Anyone can download the Map Packs if they purchase them, but you need the game to install and play them
Owlient makes the game Howrse.
Game Shark is a company all on it's own, so Game Shark makes Game Sharks.
They do not get any Map Packs and also will not get the new call of duty game MW3
Yes the map packs for the PC game call of duty world at war were free with the software upgrades The call of Duty Black Ops PC game must pay for first strike map packs
Plain and simply: Nope.
A company that makes video games.
No but Rezurrection is LOL. Activision has a habit of releasing map packs only before a new game. After the next game is released they do not release any more map packs. The fourth Map pack for the Black Ops is the closest they have ever came (September 22 2011) to a new game release (MW3 November 8 2011 ) when releasing map packs for the older game
Waddingtons.
Never. Black Ops came out with 4 DLCs for the Xbox 360 game and now they are working on the new game at Treyarch
Valve
