When Worlds Collide

When Worlds Collide is a planned crossover fighting video game conceived by Ryan Nurse and Animatron Studios, and Nurse's first fighting game. It is similar to Nintendo's Super Smash Bros. series in that it will feature characters from various other Animatron Studios projects battling against each other, and many of its features and gameplay mechanics are borrowed from Smash Bros. Like most of Animatron's game projects, When Worlds Collide has no set release date and has not yet entered development.

Gameplay
Gameplay is almost identical to that of the Super Smash Bros. series. Instead of reducing the opponent's health to zero as in most traditional fighting games, the aim in When Worlds Collide is to knock the other player off the stage. Stages feature multiple platforms, and some stages feature gimmicks that alter the environment - for example, the Vanishing Point-themed "Tokyo Dockyard" stage takes place on several shipping containers that are re-arranged every so often by cranes. These gimmicks can be turned off in the match options.

Items will occasionally spawn during battle, helping or hindering those who pick them up. These items can include "Figurines", small statuettes depicting an Animatron Studios character. There are over 200 Figurines to collect, though some can only be unlocked by finishing Classic or Adventure Mode, or by completing certain in-game Challenges such as reaching a set number of KOs.

Game Modes

 * Classic Mode: The player fights their way through eight random stages, facing computer opponents, before fighting a final boss.
 * Adventure Mode: A story-driven mode in which Rika Natsume, the Animatron mascot, has brought the various characters into an alternate dimension to battle for her amusement. Each playable character has their own unique Adventure Mode with six stages - on Normal difficulty or higher, there is an additional seventh stage where the player fights Rika herself.
 * Custom Match: A catch-all game mode that can be played against up to 3 other players online, or computer opponents. These can be either Stock Matches (each player has a set number of lives) or Timed Matches (players compete to get the most KOs in a set time limit), and can be played as 2v2 or as "Free-for-alls". Match rules can be customized to suit the preferences of the player(s).
 * Tag Team Match: Similar to Stock Matches, except that each player uses a different character for each stock, and so must select between 2-5 characters instead of just one.
 * Support Match: In this mode, each player selects an additional "support character". As they deal and take damage, their "Support Gauge" gradually builds, and once full, they can summon their support character to assist them in the fight, similar to Smash Bros. ' Assist Trophies. Some characters can only be selected as support characters.

Characters
The game's currently-planned roster includes 22 playable characters and 19 support-only characters, for a total roster of 41. Several characters have unique mechanics reflecting their in-universe abilities: Rei, for example, can transform temporarily into another random fighter, while Kiyoko Inoue can turn invisible.

Stages
The game is currently planned to feature 23 stages.
