Raptor: Call of the Shadows Cheats

First take enough damage so you start exploding. Then press backspace. Your ship should start going upwards as if you just beat the boss. NOTE: You will still lose all your money as well as getting a deathray.

Push Backspace during gameplay to completely refill your health. This does not refill shields.

Press Backspace during gameplay to lose all your cash and get a Death Ray gun. This cheat can be repeated endlessly.

Fly to a level that has an item fairly near the beginning(I used Bravo sector, wave six. It has those high-priced dumbfire missles.) Get the item, and hit escape. Abort the mission. All money you made in that particular mission will be lost, but you will still have the missles. Sell them at the shop for around $75000. Repeat this as many times as you like.
Note: this doesn't work with items that give you lots of money in-game. All money from those will be lost when you abort.

An easy way to refill your health or shields slowly is to set your plane to the left or right side, then let it stand there. Your health will go up steadily and your plane won't take any damage. This will not work if you start shooting.
