 Within the open world, the player can use a map and the Deuce's turn signals to guide them towards either story-advancing missions or side missions. Side missions include hot-rod races against a demon, defending Eddie's allies from a pending attack, or helping a cannon operator spot his targets. There are about 23 main missions in the story with 30 side missions that the player can optionally take. The player can also explore the game's world to find statues bound in leather or chains that can be freed to gain a health boost for Eddie or to reveal part of the game's backstory, and can look through special telescopes at vistas or complete certain jumps to earn additional Fire Tributes. The player can also find monuments they can raise that unlock an additional heavy metal song from the game's soundtrack that can be played on the Deuce's radio, "The Mouth of Metal"; the player can further customize its set list with songs they have been rewarded with or have collected.
