This is the fastest solo Beast time on The Slab, and the only map other than Trenches to be under 10 minutes as far as I know. Under 9 minutes is possible if everything went right.
i dunno but id be agree if this is called something like "less than 10 minutes solo challenge" beast. It is hard as it looks like, but for the rest of the maps should be "less than 13 m" since the average is +20 min, i can know it on fact:3
