Counter Blox is a team-based FPS where you are either chosen to be Terrorists or Counter-Terrorists. As a Counter-Terrorist, you must defend the bombsites against the Terrorists, making sure they don’t get the chance to plant the bomb. If they do, you have a very limited amount of time to defuse, otherwise it may detonate and the Counter-Terrorists lose the round. Purchase new weapons with money earned the previous round and do whatever it takes to stop the other team from winning.
You can even take part in the Deathmatch game-mode, where there are no teams and it is every man for himself. Choose your weapons here wisely, as any wrong choices may give your opponent the upper hand.
