Project Athena is the first expansion of Last Aurora. Project Athena, the first sentient artificial intelligence, decided to rebel against its creators by activating the nuclear missile launch sequence. This led to the complete destruction of the planet, causing the Ice Age that affects the few survivors today. The players have lost the ship Aurora and must cross a new area while battling Athena, the AI ​​that destroyed the planet.

The game introduces new maps and mechanics: a new type of survivor, the Android; a new enemy type, the automatic turret; a new amazing resource, the nuclear battery, which allows to activate unique power on convoy cards; the energy weapons, which work like the standard weapons and only use one fully charged battery instead of an ammo to fire and the Alert mechanic, which represents the attention each player receives from Athena's Armies.
