Challenge games

I will appreciate Endless Mode. Particularly, it'll provide more chances to pick up weapons you can't get otherwise - celestial, etc. I do wish that some of those weapons were more rewarding though, for the difficulty and rarity in obtaining them, though.

Right now all weapons seem similarly balanced. I feel like weapons won in battle should be more rewarding, to feed the loot frenzy, and weapons found, being yet rarer, should be yet more rewarding.
