First, let's make sure we all understand the game:
1) All heat, crowns, and crystals collected are not divided up, but rather credited equally to the entire party. (No need to rush or fight for the biggest piece!)
2) Materials are distributed round-robin as they are picked up. (This seems to be mostly true, but I'm not entirely sure.)
Pros of going solo:
1) You get all the materials. (And I swear, it seems like the game drops better materials as a reward as well!)
2) Takes longer to complete a level, so you get more playing time for your money.
3) Game adjusts to easier play, so not quite as hard as it seems.
4) Don't have to wait around for people going off on their own or screwing around.
5) You get all the health pills, tanks, and other goodies that make play easier.
Cons of going solo:
1) Takes longer, which might bother those who see play as a work/grind to earn money.
2) Harder, so you might die (lose heat) or it could cost more if u revive.
3) Lacks the social interaction of playing/chatting with others as you go.
4) No one to revive you if you die.
What would add to or subtract from this list?

Pros of going solo:
6) The only person the enemies could be going after is you, so it's easier to predict what they'll do.
7) It's easier to not wake up every gun puppy in the arena if you're alone.
