Real Space 3: Apocalypse Returns Cheats :
Secret - Tips
Keep moving ; do not make yourself an easy target.
It is not recommended to max-upgrade Pulse Cannon (1st normal weapon) and Beam Laser (1st special weapon) since better weapons will be available later in the game.
Search for power-ups frequently. Faster Fire and Double Fire combined provides excellent damage.
Shield improves your ship's health. Auto Rockets enhance the two homing rockets you fire when you use your normal weapon. Both are useful throughout the whole game.
It doesn't hurt to retry some missions to earn money for upgrades. Look out for Cash power-ups instead of focusing on the objective since you have already completed the mission. Choose missions that have a lot of small enemies. They drop Cash power-ups.
When fighting large fleet-ships, try to loop around the ship and/to avoid the turret fire.
When you are piloting UFS Antaris, beam lasers from large fleet-ships do not have an effect on you. So do not bother to dodge them.
If you are using weapons (normal or special, normal more recommended) that can home in on the nearest enemy, use them often to find out where the enemy is, especially in missions where the radar does not display the enemy.
Glitch - KFS Vengeance Handicap
This only applies to people playing Mission 36: Vengeance Sweet Vengeance or Mission 40: Vengeance Returns.
If you are just aiming to complete the mission/game and do not want a challenge, you can hide in any of the four corners in the map. KFS Vengeance cannot fly into the corners and has to turn whenever it nears the corner, hence rendering himself unable to attack you. When he comes near, take your chance to shoot him with your special weapon. It does take some time to defeat Vengeance if you use this method, but at least you don't have to avoid his deadly fire.
