This app allows the user to simulate the motion detector used by the Colonial Marines in the film Aliens. In setup mode, you can select different sized blobs, then click on the screen to create blobs to show the detected object/aliens. The blobs can be set to slowly move towards the user's position.
When playing role-playing games, such as mothership, the app can be used standalone or linked to others on the local network. In this mode, the GM (Games Master) can broadcast the position of their blobs to all the Players on the same network.
