free demo to try the game out

This is for complaints of players getting hydraulic pressed or thinking the controls are bad or "this isnt sf" so they have a way to check first what are they going to play. this avoids them from just ragequitting 0.4 hours into normal sfd and leaving a bad review. and refunding the game out of pressure from 2 hour refund policy of steam.

what should it include?

it should showcase the controls and main mechanics atleast.

either locked to 1 map and 3 bots max. either locked to only playing some challenges. either only being able to play a campaing. any of those three could work. as long as they atleast showcase the controls. of course the tutorial map should be available too.

Maybe allow to edit slots or server settings so they are prepared for hosting if they really like it,

to incentivize buying the full game: "Server browser" "map editor" and changing skins button should make a pop up appear saying "unlock le full game to do this!!!!"
