If you're smart with your dash moves, you can take out multiple enemies by jumping to a square. If there are multiple enemies around you when you land, so long as they're in range of your knife, you'll stab them all. On the flip side of that, getting surrounded in normal play is a terrible idea. You can only attack after a move, so if there are enemies around you, you're going to have to move away and then back in to attack them. That leaves you open to getting shot. A lot.
