Pro The definition of emergent gameplay
The amount of features is basically endless and you can use whatever you have at hand to complete missions through the city:
Money? Hire someone to do it for you.
A "Friends" ray? Hypnotize the bouncer and let him tell everyone that you're good to go.
A "Wall bypasser"? Teleport in, do your thing, teleport out.
A mine? Leave it at the front door and give it a knock.
A rocket launcher? Just blow it all up.
You're a Gorilla that can't speak English? Free your comrades from a lab and ask them to help you raid the place.
Do you have to kill a gangster? Lure him to a rival's territory and let the gang do your job
