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
Fourth round introduces the first boss. Fortunately, this is easy compared to some of the later ones. 2 light armoured wagons patrol on northern side of the stage. Normal enemies appear from sides and it's easy to shoot them down very quickly.

1 player tactics
 * Move to the middle of the long corridor north of your headquarters. Taking care of enemies appearing from both left and right of you, assuming you have quick reaction time, should be easy, especially with a tank with 1+ weapon upgrades.
 * When there are no normal enemies left, shoot a hole (preferably from tank spawning position to the north) 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. Best place to make those holes are from player respawning spots right next to HQ.

Round 5
This level has quite a tricky design with no larger fire corridors to shoot the enemies from, unless maximum firepower which allows to create a decent fire corridor. The saving grace is that the enemies run out of forces fairly quickly. End of round 5 introduces a flame tank, which, fortunately, is the only one in this round.

1-player strategy
 * Since the first enemies appear on the left, drive the northwest side to destroy a few of them and then retreat back near the HQ, below the thick brown wall which most of the enemies attempt to shoot through.
 * Soon, small barriers on both sides are probably shot down. If this happens, retreat just above your headquarters and continue to hold position there.

2-player strategy
 * 2 players with combined firepower can make a fire corridor just north of headquarters which becomes hard for the enemy tanks to penetrate. It's advised for one player to be 1 large tile south of other to prevent accidental kicking with each other's bullets.

Round 6
This stage features some water bodies and lots of buildings. Your base is fortunately heavily protected.

1-player tactics
 * Immediately move near the middle of the stage and make a fire corridor there. Don't worry about the left side yet. Some water in here lets to kill some enemy tanks even before they shoot their way across. Most of the enemies are breaking their way into your fire corridor so that they can easily be shot down.
 * About midpoint, enemies are also starting to appear from southern point of west side and also in eastern side, forcing you to keep your attention to these positions. Moreover, enemy tanks also start to break through the building between 2 westernmost water bodies. When enemies are starting to break through, be ready to retreat when necessary. Fortunately, there's still heavy protection around your HQ, but eventually you have to take down enemies threatening it.

2-player tactics
 * Player 1 should drive to he left side and player 2 should go to fire corridor described in 1-player tactic.
 * When enemies on sides start to appear, player 2 should stick to the fire corridor while player 1 should take care of anything slipping past player 2.

Round 7
A moderately challenging level. Most of the enemies either tend to drive to the small central area but a few coming down along sides of the map, leaving the base quite vulnerable from all 3 sides. Fortunately, this round isn't a very long one and in 3rd part of the end of the level, jeeps show up which generally aren't that dangerous.

1 player tactics 2-player tactics
 * First drive north, allowing you to take down a few to several enemy tanks soon after appearing, then retreat near the base and stay in the middle. If you want, you can shoot a path down the middle, allowing you to destroy enemies wandering into small central area in much shorter time, although then you have to keep eye on both the middle and edges. When barricades near the edges are breached, things can get bad for you. Hardest part of this stage is to deal with armoured tanks which follow quickly after normal tanks.
 * When most of tanks are destroyed, jeeps appear for the first time. Jeeps are very fast and always moving, making them hard to hit. However, their firepower is low and they pose a small threat to HQ and your tank, allowing you to wander around the map a bit more.
 * It's generally better if one player stays just north of the HQ like in 1-player mode while second player drives north to, destroying many of the enemies quickly.

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.

Round 9
This level is fairly easy. The main threat comes from armoured tanks at the beginning of the stage. They'll soon be replaced with basic tanks. In a final third of the stage, light missile launchers make their first appearance.

1 and 2 player tactics
 * It's best (for at least one player) to stay a bit north of HQ. First part of the stage is the hardest one and it's better to eliminate armoured tanks as quickly as possible, minimizing the range between them to take them out quickly. Basic tanks following that is much less of problem.
 * Pay in mind when light missile launchers show up, it's better to stay out of their line of fire when they're stopping. Allowing them to reach your base is fatal because they can destroy it in one shot. In this round, however, they're easy to eliminate.

Round 10
Steel walls with some bricks dominate this area. At the start of the round, you'll be greeted with several flame tanks. As battle progresses, they're replaced with fast tanks mixed with armoured tanks. Near the end of the stage, basic tanks with fast tanks show up.

1-player tactics
 * Move a bit north of the headquarters and clear the way to get a long firing corridor which most enemies have to pass. Having a 3rd weapon upgrade is very handy in here, since it allows to make a passage to the easternmost side.
 * Try to eradicate the initial flame tank wave quickly, especially those on the right side. After that, armoured and fast tank combination should provide quite a challenge. When bricks on the east aren't destroyed yet, you should stay near the firing corridor.
 * When the bricks on the right are destroyed, it becomes much harder to defend the base. Retreat near your headquarters and keep eye on both sides, especially the right one.

2-player tactics
 * One player should keep the eye on the firing corridor while other should advance the northeast side of the map. When brick wall on the east gets destroyed, second player should retreat to the southeastern corner while the first player should keep hold of its position.
