OUTL1NED is a manic One-Dimensional arcade shooter where you last as long as you can while enjoying a colourful lightshow in the background. Even though enemies can only come from 2 intense directions rather than 360 flaccid degrees, you will have to focus to keep the pressure at bay and manage which direction needs your attention. You will be challenged to manage your constantly-regenerating ammo and collect a variety of diverse upgrades as you go in order to last as long as you can. Battle a variety of colour-coordinated enemy types that will vary in speed, health, and visibility that will force you to make tough decisions as they close in. Enemies aren't the only danger as you will occasionally pick up debuffs that will obscure your vision and change up how you see the world. Compete to get the highest score globally on the global leaderboard.
