Swamped

You look around frantically. The best way to deal with being outnumbered is to use the environment as a weapon, but you don't know this city well. Hells, they probably know it better than you.

Which suggests your best bet is to use that familiarity against them. They'll make certain assumptions, and if one of those assumptions is wrong, it might catch them by surprise.

For instance, they might well assume that there isn't a gaping hole in the middle of that street to your right. You run over it, passing by where it's narrower so it looks like you're just running across it. If they're a little more careless...

Well, one of them was. The other's still tailing you. But you spot something against a nearby house - a metal cover. Probably what's supposed to go over the hole. You make a run for it and grab the cover.

It's heavy, but it also rolls fairly easily. You give it a little shove and it starts heading for the other gangster.

It takes them a bit to react, but they manage to get out of the way in time. Still, one-on-one is better odds than two-on-one. And while they're wary after that close call, they're also unsettled. This seems like the best time to make a move.
