Play as Miles Morales in Grand Theft Auto IV: The Complete Edition, moving the way he does in Insomniac's games. Before your first Play, setup reads Miles's Classic Suit model, its textures and his power sounds from your own Marvel's Spider-Man: Miles Morales install and builds him as a GTA IV character. Nothing from either game ships with the mashup.
Open sandbox: you start on a Liberty City rooftop with every power unlocked.
Web-swing like Insomniac's Spider-Man: hold RT (or Space), even from the street. Miles webs to real building edges along the avenue, builds speed through the bottom of each arc and chains web after web while you hold it. Let go near the top of an arc for a boost.
Traversal camera: follows the swing, pulls back and widens with speed (mouse or right stick to look).
Point launch to the ledge you're looking at, then perch and launch off it. Web-zip bursts in the air.
Wall-run up buildings, then stick to walls and crawl on them, or jump off them.
Dodge rolls, web strike (zip in and kick), web shooter (web people up).
Spider-strength: every punch launches people and shoves cars. No fall damage, superhero landings.
Venom Punch, Venom Jump / Venom Smash, Venom Dash and Venom Blast, with Miles's own venom sounds.
Camouflage: Miles turns invisible and the police lose him. The police escalate with the chaos you cause.
Suit radio: GTA IV's radio stations play while you're on foot.
Full controller support laid out like Miles Morales (Xbox controllers; PlayStation controllers through Steam Input or DualSenseX), plus keyboard and mouse. D-pad down (or J) shows every control in game.
Single player. Requires GTA IV: The Complete Edition 1.2.0.59 and Marvel's Spider-Man: Miles Morales (PC).
