Intruder Alert

All you know is forward at this point. Even if the world is against you. You're the intruder.

Intruder Alert is a 2D action-stealth adventure combined with multiple other genres packed into a single game. You play as a circle. A shape determined to complete its mission. Stealthily avoid other shapes, defeat them when necessary, and complete various tasks along your journey.

UNFORGIVING

Deaths are inevitable. If you get annoyed easily, this game probably isn't for you. Just know that it's a skill issue.

VARYING GAMEPLAY

From stealth to RPG to infinite runner, you'll be shocked to learn what the next level has in store for you as the gameplay suddenly changes. Be prepared.

REPLAYABLE

Play through a wide range of levels, and time yourself for each one. Try to beat your fastest time if you can.

BOSSES

Every difficult game needs a boss or two. Or three. Or four. Or five. Maybe just five. Don't worry, though; you'll have more trouble just getting to them.
