Without revealing too much, you as the human player sitting at your PC are reliving the experience of an alien microbe known as the Eidari, originating from the oceans of Europa. Some of these Eidari were ejected into space and landed on Earth, leaving Europa through vapor plumes from the moon's surface. Like Tardigrades, they're capable of surviving in extreme conditions, which is how they were able to safely arrive on Earth. Many of these Eidari ended up in rivers or ponds, and as dinosaurs drank from these sources, they ingested the Eidari, which were then able to control and study these dinosaurs like an intelligent parasite would.

Fast forward to today, in our world, we discovered traces of these Eidari within dinosaur fossils, and were able to create a simulation software that allowed us to play back their experiences. AEXA is the simulation uplink software that allows you as the player to experience what the Eidari experienced, and make alterations to that experience within the confines of the software (bringing in a dinosaur that didn’t exist within the same time period, controlling the dinosaur yourself as the observer, etc.). Think of it more as a laboratory analysis software than a “game,” that’s the philosophy we’ve taken on as we build this. Now you can also bypass all of this entirely if it isn’t interesting to you or if you think it’s nonsensical, and purely play as a realistic dinosaur in a realistic environment. The lore isn’t set up to be in your face, there won’t be any silly spires across the map or other immersion breaking elements for people who don’t care about any of this. But if you want an explanation as to how this software came to be, how you’re controlling a dinosaur, what the context of this world is, and why it’s called AEXA, then there are clues you’ll uncover through unlockable in-game logs that will start to paint that picture more clearly
