There are a total of 167 achievements on the Steam version of Counter-Strike: Global Offensive. The console versions on the other hand, are more limited and feature a far smaller achievement count. There are twelve achievements for 400 gamerscore on Xbox LIVE and 19 trophies (including the platinum) on PlayStation Network.
Most of the achievements included are directly re-used or modified versions from Counter-Strike: Source, while several (notably from Arms Race and Demolition) are brand new. There are five categories; Team Tactics, Combat Skills, Weapon Specialist, Global Expertise, and Arsenal Mode.
Each category has its own medal with three distinct levels: bronze, silver, and gold. To earn a bronze medal, a player must complete 33% of the achievements in the desired category. To advance to silver, 66%. To further advance to gold, all achievements must be achieved in the category. These medals are an indicator of experience and can be seen on the scoreboard and the player's Global Offensive profile.
Team Tactics is a combination of game winning challenges being endurance and teamwork based. For example, most awards consist of you winning a round based on a condition, number of times, or both.
