These are the tanks that the first and second players control. Player 1 controls the yellow tank, and player 2 controls the green tank simultaneously. Both tanks can only have one of their own shots on the screen at one time, and may not fire again until the shot hits an enemy or collides with a wall. Unless a force field is surrounding the tanks, preventing them from taking damage, they can be destroyed by one enemy bullet. If one player shoots another, it will prevent the other player from moving, although it will still be possible to turn and fire.
This is the weakest enemy tank. They move a bit slower than your tank, and their bullets travel at the same speed as yours (with no power-ups applied.) It takes one shot to destroy them. They generally pose a little threat. Each basic tank scores 100 only.
This is the fastest enemy tank. They can move at a substantially faster rate than your tank can travel. Their bullets, however, travel at normal speed. It takes one shot to destroy them. These are generally more dangerous to headquarters than a player and should be dispatched quickly. Each fast tank scores 200.
This tank has the greatest offensive power. They move at the speed of normal tanks, but their bullets travel much faster, as fast as your tank can when you collect the star power up. It takes one shot to destroy them. It's highly advised not to enter into their line of fire. Although they are generally more dangerous to player, they will cut through bricks much quicker than other tanks which is especially clear in level 34. Each power tank scores 300.
This tank has the most defensive power. They can move and shoot at normal speeds. However, it takes four shots to destroy them. They start out green and gradually become gray until the fourth shot destroys them. It's highly recommended not to destroy tanks with head-on approach before you've collected 2nd star powerup. Each armor tank scores 400.
A power up will appear in one of sixteen locations randomly on the screen whenever a tank that flashes red is hit. You must touch them to collect them and activate their effects. Collecting each powerup gives 500 points to player.
- Powerups will disappear when another flashing tank starts to appear.
- The 4th, 11th and 18th tanks in the level are flashing ones.
There are a few different types of obstacles scattered around each stage. Knowing how to use them to your advantage is the key to your survival.
