About Intruder Alert

Intruder Alert is a 2D action-stealth adventure that combines several genres. You play as a circle determined to complete its mission, sneaking past other shapes, defeating them when necessary and completing tasks along the way.

Changing gameplay

Levels shift between stealth, RPG and infinite-runner gameplay, with the style changing from one level to the next. Deaths are inevitable, and reaching the bosses can be difficult.

Levels and bosses

The game has a wide range of levels. You can time each run and try to beat your fastest time. There are five bosses to face.
