Heads Up 7 Up

You play as Elara Voss, a skeptical student at Blackwood High, where a new drink called "7-Up X" has taken the town by storm. Marketed as an energy-boosting soda, the drink was developed in the school's science lab by a mysterious scientist before being mass-produced by the town’s local factory. However, those who drink it start acting strangely—and then they vanish, only to return as twisted shadowy figures known as The Shadow Seven.

Elara, who never trusted the drink, is now the only student left unaffected. She must survive her classes, evade the deadly Shadow Seven, uncover why the scientist created this cursed formula, and put an end to it before the entire town is lost.
