Fans of the classic shooter Counter Strike can now check out Critical Strike for iOS and Android. It plays just like Counter Strike, but is based on the Unity engine rather than the Half-Life engine.
If anything, this is basically an emulation of the game. Either way, it was very popular way back in the day, so why not give it a shot?
You can check out the game at Google Play or just go to the App Store:
