To clear an alien nest, in base Beyond Earth simply walk onto the tile containing the nest. If an alien unit is present on said tile, you will need to defeat the unit or wait until it moves. Nests yield a bounty of File:20xEnergyBE.png Energy and, with the Scavenging Virtue, File:20xScienceBE.png Science. In the Rising Tide expansion, players must manually select the option, destroy Alien Nest, in order to destroy one. Destroying an Alien Nest will result in angering nearby Aliens.
