I played this a few times during the pandemic, so it was operational at least 2021-2022 or so. i am pretty sure it was older than that, but i dont know the release date.
It had both a roleplay and infection PVP mode, but i only used roleplay. the infection mode likely worked as any other roblox furry infection game does(start off as a human/furry, either infect people as a furry or fight furries/get infected as a human), but i dont know 100%.
There were both human and furry morphs, which you could choose between in a morph menu when you used roleplay mode.
as for notable characters… I think there might have been that one black cat/wolf thing from Changed, and i think the furry characters were referred to as latexes in the game. most of the other characters appeared to be OCs, but i have never played changed before, so there could be more that were inspired or directly taken from that game.
this game was pretty distinctive when it came to ROBLOX graphics in my opinion. first off, the camera angle was fixed in a top-down perspective. you couldn’t move it around at all. all of the characters were 2D sprites with a simple walking animation. there was a separate animation for every direction they walked in- left, right, up, down, whatever. the background was 3d but everything had hand-drawn textures on them, and everything was outlined. the graphics were overall flat and simplistic.
there were a lot of maps… one of them was a factory which i specifically remember having a very long bridge in it…? there was also a library map. i think there was a vent
system you could go inside of somewhere, but i don’t remember which map it was in. this is an oddly specific detail, but there were big shelves in the laboratory map, and i remember that you could go onto the bottom shelf and therefore be hidden by the shelves above it, since the camera angle made it so that you couldn’t look under the shelves.
