Your goal in Mecha Martyr is to upgrade your mecha and kill those enemies and survive as long as you can. The best way to do this is to become stronger. You can upgrade and heal by spending experience, which you get by killing enemies. If you kill as many enemies as you can at the start, and keep their numbers slim they should not be able to over-power you, and you will be able to survive longer. If you are low on health, fly high so you don't get hit as much, and try shooting the bullets out of the air. Use the WASD KEYS to move around. Use YOUR MOUSE to aim and shoot. Press the SPACEBAR to launch grenades. Use the MOUSE WHEEL or 1, 2, 3 KEYS to select grenade. Good luck!
