Tank Force/Rounds 1-12

Round 1
The enemies are few here and headquarters is well-protected with steel walls. It's easy just to roam around and kill every enemy passing by and collecting valuable weapon power-ups.

Round 2
At some point, you'll most likely receive airstrike power-up which makes this level considerably easier.

1 player tactics 2 player tactics
 * Blast open a tunnel just the south of bushes. If you want, you can also advance north to kill first appearing enemy tanks. Retreat to the tunnel as the enemy advances. You should receive airstrike power-up about the time when enemies in the right edge start opening the tunnel. After airstrike, it's pretty easy to take care of the remaining tanks.
 * Second player should take care of the enemies appearing on the right side.

Round 4
First boss level which is easy compared to some of the later ones. 2 light armoured wagons patrol on top of the stage.

1 player tactics
 * Move to the middle of the long corridor north of your headquarters. Taking care from enemies appearing from both left and right of you, assuming you have quick reaction time, should be easy, especially with tank with 1+ weapon upgrades.
 * When there are no normal enemies left, shoot a holes to start shooting bosses, making sure that you have enough protective cover when you retreat from their cannons.

2-player tactics
 * Both players should move to the long corridor and each player should patrol either side of the stage, easily taking care of approaching tanks.
 * Take care of the boss like in 1-player strategy. Make sure that both player's firing spots are a bit spaced so protective cover would be present on both sides for both players.

Round 6
1-player tactics Immediately move to the middle of the stage and make a fire corridor there. Some water in here lets to kill some enemy tanks even before they make their way across.

Round 8
Introduction to AK-1 vehicle. This massive vehicle has 3 turrets which must be destroyed to finish the vehicle. Turrets of this vehicle shoot when they point downward. Apart from the AK-1, the only other enemies are jeeps which appear 1 at a time when all the turrets of AK-1 are present.

1-player tactics
 * Go to the west and kill the 6 first appearing jeeps right after they spawn. Do the same in the east side of the map. Jeeps generally pose a little threat to the headquarters.
 * When you don't have a line of fire to jeep and there's an opportunity to damage AK-1 turret, do so. Just remember that destroying a turret increases the maximum amount of jeeps on-screen by 1.
 * After jeeps, move as north as possible to maximize the speed of taking out the boss. Only move away from it when turret is starting to point downward.

2-player tactics
 * One of the players should do step 1 in 1-player tactics and the other one should take care of the boss right away.
