capnfapnI have an idea!
SUPER SMASH FORTRESS CAMPAIGN MODE
This would basically be a tf2 adaptation of the classic mode in ssbm. An invite team would try and make their way through a bunch of gimmicky opponents on various levels. Since the invite team will only have 6 people on it, lots of viewers can play at the same time. The cool thing about this is that people get to watch high level players deal with weird stuff, and you could get viewers to donate in order to play against them.
Here are some "stages" i thought of.
1. invite team vs bat only scouts. cp_dustbowl.
2. invite team vs plog m+m1 pyros. cp_granary
3. invite team vs shotgun only heavies. cp_badlands.
4. invite team vs battlemedics. cp_gravelpit
5. invite team vs minisentry engies. cp_snakewater.
problems with this idea that I can think of:
1. people not playing as they're supposed to. hopefully having to donate to participate will lessen the number of hilarious trolls xd
Uh, I am usually all for fun and gimmicky stuff, but this doesnt seem very well thought out.
