Batman: Arkham Origins
Closest I came was fighting Bane on the roof but was short by 1 as I mistimed the attack.
So very very annoying :P
Shame you can't do it on 100 to 1 training scenario
But if late, wait till you destroy Blackmask's cannisters the last one will show a bird icon on the map, you get to fight 20+ normal mobs, no shields, no guns, no heavies but some have knives but can be punched and kicked.

You can use cheat engine on this one as well, set the number of variations to 14 and use the trainer for easy combos or just freeze free flow with cheat engine and at some point you'll get 15 variations.
