Interplanetary Hunter

You can move your mecha freely, and you need to kill enough robots to challenge the boss. There are different types of weapons to deal with different enemies, for example, the super laser weapon is better to kill massive troops. You can gather all the enemies, if you can, and activate the super weapon. Meanwhile you should activate the defense system, but you also need to move to avoid the skills of the enemies, otherwise you will be defeated. If you survive you will gain lots of killing points. But pay attention, if you choose the machine gun weapon, you can only deal with one enemy so don’t make too many pulls.
