SCP-294 is an anomalous vending machine capable of providing any beverage the buyer asks, it requires a coin to operate and can choose a variety of drinks, literally anything you want.
SCP-294 unlike SCP - Containment Breach, only gives a positive or negative effect not to be confused with mixed or technical effects which are staff usage only or give the user a positive effect with a negative effect.
When approaching SCP-294 a prompt on the users HUD appears telling the player they've approached SCP-294. To use SCP-294, the player must be holding a coin and by pressing [~] they can open the console and then simply type ".scp294". It will then dispense a random positive or negative effect. Keep in mind some effects can have a different intensity to it as well as a chance to only get an empty cup in return so everything is complete random chance.
SCP-294 can be found in the Entrance Zone's upper story PC room.
