Hints & Tips

Easy money
Gain enough money to buy the Blaster. You will not have this chance until the fourth level. Buy it, then make your way to any battle arena and equip the Blaster; the Marder III is suggested as most tanks will not have it equiped. Then select the Difficult tank to battle. When the battle starts, move up to where the battlefield begins and shoot the Blaster rocket. If you did not turn or do a thing, you should at least get a near hit. Adjust it until you hit the enemy and watch his power go down to nothing. Do this four times to receive 2000 gp. You can get 500 gp for a tank if it has already been taken out, or 1000 if you have not taken it out. Try this often. It takes some practice, but is worth it.

This trick needs a Long Shot and Gloonstat. Reach the Expert Arena and play a Web Battle within the difficult setting. As soon as the game starts, shoot him with your Long Shot to knock him out of the arena. You will win 1200 gp for the first time. If you win once again, you recieve 600 gp.

All gear in battle mode
When you first start out in story mode, select a tank and battle with it to get money. Then when you have plenty of money go to the shops and buy needed equipment. Equip it and save the game. After this, sell it and buy different items. Do this again until you have all the gear you want. Once your done, go to battle mode and select "Custom Tank". You will now able to customize it with any gear you want.

Angel Wings special part
Finish the game completely to access the Angel Wings part. These will allow you to fly without using much fuel.

Devil Wing special part
Win every arena battle to earn the Devil Wing special part.

Blaster
The name of the Blaster weapon is a misunderstanding. It does not really fire blasts. It really launches SCUDs that deal severe damage to opponents. Just keep this in mind when you see the Blaster in a shop at one of the towns.

Beating the Last Master
Remember that the Last Master has three forms. The first two are easy just shoot him and kill him. The last form is hard. You have to shoot the tank under him and demolish it. He will fall down. Make sure you hit his face when he is falling. His armor is weak when you shoot him. But it is hard to shoot him when he falls down because the gears keep moving. So be careful, as they could crush you. When the boss gets up, the tank that is under him regenerates and you have to destroy it once again. Repeat this until he is beaten.

Alternate route
When you reach the point where you have the option to execute the Naldnick level at night using night parts, do not do it, If you do, you will have to do a difficult city level where you have to destroy blockhouses without any damage to the town. Instead, do the other level you can have access to. Then, do Naldnick at Daytime. You will skip the blockhouse level.

Black and fire paint job
First select the BHE tank, then select the urban paint job. It should be black with fire on the front.
