Daring Stunts
The Daredevil game should most definitely be open world. This opens up opportunities to find random encounters, find information for cases you’ll work in the day as Matt Murdock (more on that later), and go from mission to mission. Each sandbox game gives you different ways to travel. GTA and Saints Row have you jack vehicles or super jump around a virtual recreation of Steelport. Infamous lets you either climb or use your superpowers to ascend high in the sky. The Batman games give you a grapple gun, your cape, and just let you glide around Gotham.
Whether he’s suited up as Daredevil or in his civilian clothes, Matt Murdock is a master gymnast and amazing athlete. He can parkour like nobody’s business, and his billy club (disguised as a blind man’s cane) holds a grapple in it that allows him to swing around Hell’s Kitchen, if he’s so inclined. The grapple and his parkour should be his primary means of getting around Hell’s Kitchen. Car surfing would be viable, but not all that safe or reliable. Parkour, along with the grapple, could also lead to fun race challenges or stunts that require the use of both. Time to get fancy!
Doing first person parkour and stealth wouldn’t be much of an issue following games like Deus Ex and Mirror’s Edge. Combat, on the other hand, will be a tricky beast. Some first person games pit you against one enemy at a time, while others will just open the floodgates and tell you to go nuts. Given Daredevil’s blindness, something like Arkham Asylum’s lightning bolts on top of attacking enemies’ heads would be beneficial. Soundwaves of differing intensity would help differentiate between an armed enemy, a shielded enemy, and so on.
