The following is a list of mechanics that separates Prism Cross from the stock standard platform fighter. Read on!
Every character in the game has a universal meter called the Prism Gauge, which builds up overtime by attacking or getting attacked. This gauge can reach a max of 6 charges, and can be consumed in order to perform several new actions. The ways in which you consume them are listed as follows:
A third attack button has been implemented, called the "EX Button". While in platform fighters like Smash your main two inputs for attacking are A and B (Attack and Special), in Prism Cross, you have what you can consider a "C" button, called the EX button. When you have two charges of gauge or more, you can use this button + a direction in order to perform one of your character's EX moves, which are brand new techniques that are more powerful than the usual special moves.
Brand new mechanics are in, such as Prism Cancelling (similar to RC from other fighting games, allowing otherwise impossible combos to be possible) and Bursting (an emergency "get-off-me" technique), all of which leverage the Prism Gauge's charge in order to be activated.
