Riffle Effect is a shooter that offers two different points of view. Take command as Gatto, a lone mercenary who finds himself stranded after his spaceship crashes on the planet Ureun, leaving his indispensable partner Rose incapacitated. Tasked with repairing Rose, Gatto must use a combination of a variety of skills and equipment to defeat his opponents.

The journey begins after he teams up with Rose, an aerospace artificial intelligence, on the orders of a captain who has enlisted his services. However, their partnership takes an unexpected turn when their spaceship falls into a wormhole, resulting in a noisy crash landing on Ureun. This untimely event not only causes their ship to lose power, but also deactivates Rose's vital functions.

Determined to set things right, Gatto sets out on an expedition through the mysterious terrain of Ureun with the dual goal of recovering Rose and the spaceship. The ability to switch between two different perspectives during combat scenarios is provided, selecting an overhead or over-the-shoulder view as needed. This strategic choice allows you to navigate treacherous, enemy-infested terrain, skillfully dodging traps and honing weak points. Using precision and calculated tactics, you will need to defeat your enemies to progress in the campaign.
