Counter-Strike: Global Offensive

The game is going to be a competitive shooter like CS but at the same time it will have Dead By Daylight horror elements to it. There are 13 players in a match, 6 people on team "AGENT", 6 people on team "CHAOS", and one "L.U.R.K.E.R." At the beginning of each match, all players except the Lurker buy guns and equipment with their money while the Lurker spends "D.R.E.A.D." Points to gain abilities. Some abilities are used for movement, some are used to scare the shit out of other players. and some are used for misc abilities like blinding and a bigger minimap. The game ends when one of the three sides gets three wins. The L.U.R.K.E.R. wins when he is the last man standing, The Agents win when they kill the enemy team and the Lurker or plant the bomb and extract, and the CHAOS win when the enemy team and the Lurker are killed or when they defuse the bomb and extract. The game will be played in "HIVES" where the Lurker lives and reproduces and the maps should have a fleshy, uneasy, and overall creepy atmosphere. The Lurker would be stronger because people have to buy special "SMITE" rounds that can damage the Lurker but he will still be tanky. Also, the Lurker is going to be able to hide inside of closets and things and the only way people will be able to sense them is by going near the closet and listening for feint breathing. That is the description for the game but what I wanted to ask was one, what I should name the game, and two, if anyone would like to help me.

Hi! I am a beginner just starting to learn about the gameplay mechanics, but I have realized: I have a hard time picking guns to use. I have only played Dust2 up until now, and I heard people say never use SMG's in Dust2. Does this only apply to Dust2? and also, what rifles are the best for people with bad accuracy?

PS: trying to see if I can get the hang of other maps.

Thanks!

The skins in Counter-Strike: Global Offensive are awesome. I only like camouflage skins though.
