The idea is pretty nice, and both options are appealing to me. Besides, anyone would be able to run it even if they don't have a capture card, since that part of the game is not blocked for PS4 streaming.

Are there any plans for creating an Uncharted 4 Survival mode leaderboard? Since Uncharted 2 and 3 co-op modes had their own leaderboards I believe it would be interesting to do so with this new Survival mode in Uncharted 4.

Yeah, I usually play using turbo for that exact reason but I thought it might be considered cheating for speedruns.

Would Turbo Mode be allowed during a speedrun? The rules don't say anything about it.
