Capcom is readying some new DLC for Dead Rising 4 that is set to hit on April 4. It's called Dead Rising 4: Frank Rising and it finds Frank joining the ranks of the undead in this single-player story content release.

This content will be included in the game's season pass or separately for $9.99 (USD). There is another piece of DLC that was mentioned today and that is Super Ultra Dead Rising 4 Mini Golf. It uh... it's mini golf in Dead Rising.
With multiple holes of pure wanton destruction, in Super Ultra Dead Rising 4 Mini Golf players will flip zombies the bird as they navigate the greens in the Willamette Mall and surrounding town. Unlock specialized golf clubs, costumes and balls as Frank West provides play-by-play commentary for swings, birdies, and shots. Collect Power-Ups to take the game to the next level and take out zombies with explosive style while keeping swings low and the kill count high. Hone course skills to perfection in single player, fight for the high score online in a 4-player multiplayer, or join friends in your living room with turn-based co-op.

This is also a part of the game's season pass or can be purchased separately for $9.99 (USD). It seems as though all of this content is confirmed for the Xbox One and Windows 10 Store versions of the game. I presume it's also coming to the Steam release as well given that it also has a season pass and a deluxe edition.
