In the game you will have to free the treasure from the invaders, which are located in different locations. The peculiarity is that neither you nor the enemy can move. But you have a weapon that ricochets bullets quite well. This helps to get opponents who have taken cover behind boxes, walls, are in another room and other hard-to-reach places. The passage of each level is very fun and exciting, as it is sometimes difficult to predict the full path of the bullet.
