Modes
Slap City game modes are listed here.
Story Mode
Story Mode is a single-player game mode which includes story campaigns for each of the first 8 characters (from Ittle Dew to Asha). There are 17 "missions" total, which include 12 platforming stages (2 of which are optional) and 5 versus battles. Each character has their own story with unique dialogue cutscenes.
There are various collectables to pick up scattered around the platforming stages, which unlock character costumes, selectable music, or useful info and tips in the "Extras" and "How To Play" sections. Upon completing Story Mode, an additional outfit is unlocked for the character used.
Arcade Mode
Arcade Mode is a single-player game mode in which players fight through a series of matches against CPU opponents in various setups. There are 10 rounds in total which increase in difficulty as the player progresses. Match setups, which include 1-on-1s, teams battles, and free-for-alls, are fixed, but the opponents fought are randomized up to the final battle. There are 7 difficulty modes, ranging from Beginner to the hidden Devil Insane (selectable by trying to increase the difficulty continuously past Insane).
Smack the Crystals
A time attack mode in which players try to pop all of the crystals in a stage as fast as possible. Each difficulty option is a separate stage, but the stages are the same for each character. This mode is also used in Arcade Mode, match 8.
Versus
Battle
The standard mode for playing matches with other players locally or CPUs in a timed battle with lives (also called stocks). Any players who run out of lives are eliminated from the match, and the final player remaining wins. If the time limit is hit, the winner is whoever has more lives or, in the case of even lives, has the least damage on their live. The time limit and lives count can be changed in the options menu, the default of which is 8 minutes and 4 lives, respectively. Up to 4 players or CPUs can enter a battle together.
Free-For-All
Slap Ball
A teams mode in which players knock around a ball (and each other), trying to hit it into the opponents' net. Every time the ball is hit, the amount of points gained when scoring increases. However, once the ball touches the ground, it resets back to 0.
Team Battle
Teams-For-All
Training
A game mode which features a special menu with options for viewing hitboxes, setting character health, changing CPU difficulty on the fly, setting CPU DI and SDI levels, or putting the game in a frame-by-frame mode, which allows for advancing the game one frame at a time.
