Scenario:
At this moment, you have been teleported across several galaxies unto another planet (we'll call this planet Pmal). Once you've arrived, the aliens or "Pmaliens" explain to you that they have been invaded by a force that they cannot physically rival, because their (Pmaliens) mental capabilities develop greatly while their bodies remain ill suited for any kind of combat. They've calculated that within a years time, planet Pmal will have been taken over completely and every Pmalien will have been killed off by the invaders
They have brought you to planet Pmal because your human strength is capable of defeating their invaders and saving planet Pmal. To aid you in the fight, they have formulated a chemical that can enhance the strength of a person to a certain extent. Everything about you will be enhanced, your jump height, your speed, and overall strength, the effects will be permanent. (you won't be super-human but you will be pretty damn impressive)
The catch is that these enhanced abilities won't give you a definite upper hand in the battle, rather it will give you the power to run through all the minor minions and have a pretty evenly matched battle with the "Big Bad" in charge. ( the equivalent of a video game final boss) As with all adventures, there is a good chance you will die. So, what will you choose to do?
Accept the powers and try to save planet Pmal?(you can go back to earth afterwards)
Or, go home knowing Pmal will be taken over and an entire alien race will be exterminated?
