Survival is probably runnable; I have some ideas for strategies. If we did add a category, what wave# do you think would be appropriate? My gut says finish 5 waves (reach wave 6), as such a category would be long enough to be interesting but short enough to avoid being a chore.
Wave 6 seems reasonable. To my knowledge, there is no "final wave" like there is in Horde mode. I think the timing method should be the same as Horde; 15 minus the time in the top right.
since you can sort boards from highest to lowest we could do a survive for the longest sort of deal
I'll make the category right away. If there is a significant amount of interest, we could also do 10 waves or 15 or any other number. ItsMeCy is correct in that some leaderboards do have what Diriector_Doc called "the opposite of a speedrun;" we could add an "endurance%" or something like that, where the goal is to reach the highest wave possible, but I'm a bit skeptical of that one.
