Idea is good... but I agree with the others who say it needs work.
One thing I dislike is the real time wait limit for hatching eggs. I'd rather it be some other wait limit... like per quest completion, per # of steps, or per # of monsters killed.
For all the lazy people:
It's about cutting (making marks on your arm with a razor blade). The pain and the loss of blood actually causes a euphoric feeling.
Interesting... The third ending makes a lot of sense out of this story. To get to the third ending... get "closer" with the girl.
The hint here is the beginning: "She wrapped herself around my arm and stuck there ever since". Item wise... what could you wrap around your arm? Why would you wrap your arm with something? And what could you possibly do to cause something to stay on your arm forever after the first time?
Best endgame weapons:
1) Handgun with splitting bullet perk.
2) Rocket Launcher with 3 rocket perk.
Handgun is by far the best of the best... splitting bullet continues to split as it hits other zombies. In endless mode this means a screen full of bullets (BEWARE OF LAG!).
You start with the handgun, you end with the handgun.
It's okay. Flying around is a pain... it seems the only ideal way of movement is forward while maintaining a constant spray of ammo that completely surrounds your ship.
