The Earth is under attack by aliens. They have started disasters all across the globe, including volcanoes, tsunamis, and earthquakes. The Redmond Institute sent Alpha Team to stop them. They failed. Your mission is to find out what happened to Alpha Team, and continue their mission to the underwater alien base.
Arc of Doom is an educational adventure game; pick your stats, pick a partner, (your choices will change the story) and explore the Redmond Institute. Talk to everybody, inspect everything, and watch your back.
