Mission 12, mission 12. The level that starts off with the rapid-firing red tank in an open space with you, and the level that introduces the deadly green tank that rapid-fires rocket-propelled shells – and that rebound twice. As with most levels that seem deadly at first, they become relatively straightforward when the right tactic & strategy are applied.
As with before, when you come face to face with a red tank, an offensive tactic is often effective. Here, start off by seeking the red tank directly and immediately fanning out all five rounds, leading and lagging the red tank at the same time. Since the red tank doesn’t try very hard to evade your shots when a direct line of sight is available, this will usually take it out.
Next I usually proceed to the upper right end of the barricades to tackle the green tank near the upper right corner. At this position, that green tank will usually try to hit you with the first rebound by aiming at the upper wall. Therefore, if you also try to do the same to it via fan-and-rebound, you will be able to cancel out all its attacks, and in the process take it out too.
Then I usually just sit there and wait for the remaining red tank to approach and take that out the same way.
Finally, we’re left with the last remaining green tank. Here you would employ tactic #5 in General Strategy against Green Tanks. Fortunately, the geometry of the arrangement is such that you will be pretty safe as long as you are on the northwestern side of the battlefield. Therefore you can wait for a good opportunity to sneak into a line of sight with the green tank and fire directly (oh yeah, and run!). The opportunity is when it is about to fire its next shell, as that is when its previous shells have already traveled some distance on the screen, allowing you to see their trajectories clearly, and when its next shell will take a short while to reach you due to the distance. Yes, they are rapid firers when compared to other rocket-propelled-shell-firing tanks, but not to ordinary ones.
Notice that the potholes didn’t play a role in this strategy. Also, you are able to take the tanks out one at a time, due to the geometry that constrains the effectiveness of the two-rebound shells, and to the fact that when an enemy tank seeks you out in this game, they almost always do so by direct approach, i.e. they rarely take a longer path in order to sneak up behind you, i.e. go around the “far” end (relative to you) of the diagonal barricades.
