CSManager is a free browser based game that allows you to build up a pro Counter Strike team and manage them to glory.
First spotted by PCGamesN, CSManager is effectively a simple version of Football Manager but instead of managing a football team you have to guide a Counter Strike roster to success.
Hiring staff, training players and playing games are the bulk of the actions you will be tasked with. The 2D map view of games allows you to see just how well your team is doing in both tournament games and Practice Clan Wars games against other real life players.
