"Yakvan!" He shoots his gun two times to you. As he shoots, as he didn't know, the bullets came back to him. He is dead. You feel more powerful. You leveled up twice. Spend your points! Your shield can take two more hits.

Kazam. You remember that his name is Yazovak. He's the "big boss" of that invasion. He was studying you to know how to deal with the humans, but you woke up just when he started. He is small- which may make you think he is easy. You need to gather a new weapon to reach his level.

You keep searching, and you find the house you found first. You decided to search even more, and find the BFG. It does 500 damage- it has up to 3 ammo in all the planets, so be careful not to miss!

I do a happy dance, then rocket boost to the next planet for progress, and search for more houses, and enemies to destroy to become powerful enough to defeat Yazovak.
