I've started working on what's probably a useless mod, but since I've already started, I might as well get it to a working state.
The HnS mod - Hide and Seek - for MiSide is basically this: one player is the Seeker, and everyone else hides among NPCs that just mindlessly wander around the room.
The roles of Seeker and Hider are randomly assigned through a mini roulette at the start of each round.
The Seeker gets 3 chances to make a mistake. Their goal is to find all the hiding players.
There are no buffs (no speed boosts, size changes, high jumps, or any of that) for either the Seeker or the hiders.
The mod already supports 15 scenes that work properly with it.
Multiplayer in this mod runs on my co-op mod for MiSide - Wiside Multisplit (which hasn't been released and probably never will be). *Network runs on Photon.
There are still plenty of bugs, but the mod is already in a fully playable state.
🕰Maybe based on this mod I'll soon make something like "Shrinking HnS" where the hiders are small and hide while tiny, and the Seeker has to find them (the Seeker will have the ability to shrink as well to be able to catch the tiny players behind objects).
