Gameplay
The gameplay would be derived from Super Smash Bros, with elements of PlayStation All-Stars. Battles can be fought in both damage-based and HP-centric battles. A character's moveset will consist of four directional melee attacks, three directional smash attacks, and four special moves. Each character will recieve two finishing moves: a Super Smash, and a Final Smash. A Super Smash is derived from the Super Move mechanic from PlayStation All-Stars in that it can be accessed through a chargeable meter. However, it is more similar to a Final Smash from Super Smash Bros in that it will deal a great amount of damage, but it not guaranteed to earn a KO. However, the Final Smash, accessed through a Smash Ball like in Smash Bros, will guarantee a KO as it operates identically to Battle Royale's Super Moves. Final Smashes can range from cinematics, transformations, and directional/trapping moves. A new feature to either series allows players to select two characters before battle, one to serve as a leader and the other to appear as support. Both characters can be swapped out during battle, much like in the Marvel vs Capcom series. Amiibo can also be used in battle in the Nintendo Switch version, where they can either be selected as battle characters before battle, or they can be summoned as Assist characters during battle if players pick up the "Amiibo Support" item. Both the Nintendo Switch and PlayStation 4 games support cross-platform multiplayer.
