About CS Online

CS Online brings the legendary Counter-Strike experience to your web browser. Join global servers and engage in the classic struggle between Terrorists and Counter-Terrorists. This faithful adaptation recreates iconic maps like Dust 2, Aztec, and Italy with surprising accuracy. Buy weapons at the start of each round—from Desert Eagles to AWPs—using money earned from kills and objectives. Whether you're rushing B site or holding the long angle with a sniper, the tactical depth remains untouched. It's fast, competitive, and completely free.

How to Play

Choose your team (T or CT) and spawn into the map. Use WASD to move and Mouse to aim/shoot. Press 'B' (or designated buy key) at the spawn point to purchase equipment. The goal depends on the map: plant/defuse the bomb or rescue/guard hostages. Eliminate the opposing team to win the round instantly. Communication and teamwork are key to victory.
