If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
A new wave of enemy units is approaching your soldier. Just like in the previous episode, intelligence has done its job superbly. Every enemy unit has been identified and tagged.
All that rest now is to get the instructions to your soldier. Type in the codes and your warrior will do the rest. The life of your soldier is in your hands so be sure to keep one step ahead of the enemy.
