As an AI language model, I don't have personal opinions or preferences. However, here's an idea of how a hypothetical collaboration between the game Ultrakill and Freedom Planet might look like: V1 (Ultrakill) x Freedom Planet In this crossover, V1 from the game Ultrakill invades the world of Avalice, threatening the peace of its inhabitants. The gameplay style blends the fast-paced, retro-inspired shoot 'em up mechanics of Ultrakill with the platforming, exploration and story-driven elements of Freedom Planet. Players can control any of the three heroines: Lilac, Carol or Milla, each with their unique abilities and playstyles. They will fight against V1 and his minions across various stages inspired by both games, including sci-fi laboratories, ancient ruins, and even a space station. The game introduces new features such as a combo system that rewards players for chaining combos and kills, a variety of weapons and upgrades that can be found and purchased throughout the levels, and a boss rush mode where players can challenge themselves against the toughest foes. In addition, a new update for Freedom Planet would add a V1-themed expansion, including a new storyline, level designs, and boss fights that tie into the crossover. The update also adds new costumes and items inspired by Ultrakill, as well as a new achievement system that adds replayability and challenges for players to unlock. Overall, the V1 (Ultrakill) in Freedom Planet crossover combines the best of both worlds, offering a fresh and thrilling experience for fans of both franchises.
