Retro City Rampage follow up, Shakedown Hawaii, is set to launch in Q1 2019 on PS4 and PS Vita with cross buy. The game is also scheduled for PC, Switch, and 3DS so barring any exclusivity deals expect those to arrive near the same time.
“The good news is that it’s finally content complete,”explains Brian Provinciano from developers Vblank via the PlayStation Blog. “However, it still has a few months of playtesting, polish, and platform certification left. ”
The game includes a Story Mode with side quests, Arcade Challenges for “fast paced pick-up-and-play action”, and Free Roam Mode for when you just want to blow crap up.
