The game that we started in the last tutorial is now available in the Google Play market called “Negev Defense: Training Sim”. In this game you play a new cadet in the fictional Israeli M.T.M.D (Manual Targeting Missile Defense) Unit. Your job is to complete a set of 15 different simulated scenarios. In each scenario you will have to intercept and destroy all enemy missiles before they reach their targets.
The game can be downloaded from this link.
