View treasure chests locations on the automap
To see the locations of treasure chests on the map, you must first activate every teleporter on that particular planet. You will receive a message when you walk through the last teleporter. Treasure chests are shown as a yellow dot on the map.

Easily weapons and armor experience
Go to any area where you can kill the enemies with one shot using your blaster. Rosa works the best, but you can try other planets if you want better items. You will always get the same weapon/armor experience no matter where you go and no matter what you kill.
