At the time, you'll fight another mini-boss, Allen O'Neil. The gaps are very long, requiring you to jump between them from edge to edge, so time them accordingly and don't jump too early. You'll start out at the base of a cliffside that you'll have to ascend. After the Riberts is nearly destroyed, General Morden himself will appear at the cabin, firing rockets from his bazooka constantly. There is a cabin located at its side from which a soldier will appear in a turret that fires homing missiles. It will also fly to the top-right corner of the screen, where it will drop a large amount of bombs that bounce on the train randomly, making them a little difficult to dodge. Its main attack method is to launch propelled missiles which have a number of patterns, such as going straightforward or making loops, from the bottom. This boss has several attack patterns you'll need to learn. If you're missing the tank, or have a hard time getting here with it, stockpile grenades, use the lifter to get level and spam them when able to inflict massive damage quickly. There are three lifters that I recommend avoiding unless need be to dodge rockets. You should still have your tank at this point so fire upward and dodge the projectiles as they come. The second boss, is the Hairbuster Riberts,a heavy bomber. Even without the tank, the rounds fired from the Mini-Bata are slow and you have a lot of room to maneuver so you shouldn't have any issues with it. If you're quick enough, you can defeat it without letting it fire more than a single round. Like the first level, you should still have your tank with you, so just let loose upward and avoid the cannon. The first is a mini boss, the Mini-Bata, a self-propelled railway gun. Level two will have two bosses, both of which are fairly easy. Once Tetsuyuki is down, it's off to the second level! Remember to keep your tank alive during the level for added defense in case you make a mistake. If you're quick enough, you should defeat it after it fires it's first ground attack. Remember, the pattern of attacks are as follows: lobs rounds (arcing upward), upper laser (duck), lower laser (jump).

You should have plenty of shells/grenades that you've collected during the level to make quick work of this first boss.

It lobs shells upward at first, followed by a laser across the screen that you'll have to duck and then it fires an orb that follows the floor that you'll have to jump over. The first boss, Tetsuyuki, has three attacks. Tanks can take three hits to your one, so keeping them alive is crucial. For these, it is highly recommended to keep your tanks alive as long as possible. The first two levels are relatively easy and with practice, you'll probably be playing these several more times over than any of the other ones. With that being said, let's look at the levels.

Secondly, you'll be playing in "Arcade", as you have to play from the beginning to the end without continues. The achievement can be unlocked on any difficulty, but why make it any harder, right? First things first, change the difficulty down to easy.
