In Arena mode, you're presented with a spacious section of the city's rooftops, without the pressure of a creeping barrier coming up behind you. You have complete freedom of movement within this complex high-rise "arena" but you'll be challenged with a variety of tasks. Examples include finding and collecting certain items , completing a specified route within a time limit, stealing an item without getting spotted by the snipers, or - simply - killing all the enemies! Arena mode feels even more like a real city, so enjoy the views… but try not to die.
