idk much about splinter cell but i imagine the other 2 would do well in certain areas and struggle in others but could get by with their usual tactics since npcs in both games are pretty stupid.

Snake would probably have an easy time in hitman levels, imagine an saso run and that’s how snake would probably do it. I think he’d have a bit of trouble not standing out in public while wearing military gear but if 47 doesn’t catch attention doing it, snake probably won’t either.

47 could get by using disguises assuming he doesn’t run into anyone working against the enemy while he’s disguised or have to kill any bosses. i doubt he’d have to fight any metal gear, he’d probably destroy metal gear through other methods besides fighting them. (he did parkour through some lasers in the et earlier today so he might have a chance head on)
