## CHECKPOINT In some levels you will encounter a cyan animated line. It marks a checkpoint. Game will store your hull integrity, heat and score in the moment you cross the line and from now on you will restart from this point until you win or abort the level. ## BASIC RULES AND HINTS Generally enemy shots are much weaker than the enemies themselves. You can survive a lot of hits, but never collide with other ships. Upgrade ship's cooling system and engine in the beginning to lower overheating effect and to raise your chance of avoiding enemies and their shots. Buy best possible weapons (the newest ones in the offer list) and upgrade them on the highest level. Try to spend all your money. If your combination leaves some 15.000-20.000 bucks you should by some extra guns - even weaker - to maximize your firepower. Wrecked enemies and buildings do not damage you. Don't waste your time by avoiding it. However, falling wrecks kill ground enemies. So concentrate on air targets, whenever there is a chance they will fall down on other enemies. Know your level – not just formations of enemies, but know what terrain collides with you, which buildings hide hull integrity bonuses, where you can help yourself by shooting down enemies on the heads of ground units, etc. Customize your weapons for certain levels. Sell bombs before you fly outer space missions for example. They are almost useless there. But buy them back, when you fight above planet's surfaces. Do not shoot all the time with heavy energy weapons. They overheat quickly. They give a lot of power, but you have to use them wisely. Combine strong energy guns with non-heating bullet or missile weapons. Combine strong guns with concentrated aim and weaker guns, which spread shots on a wider area. Three guns pointing straight forward kill fast, but it will get you in trouble when you encounter swarm of numerous small enemies.
