It is hard to contain this epic game in a brief post, but let's try. Aeon Trespass: Odyssey is an upcoming Kickstarter release by Into The Unknown. The campaign is scheduled for September 9, and you may already check out the Preview.
The game is a 1-4 player cooperative adventure set in a sci-fi version of Ancient Greek myths. You are taking control of the Argo ship and its crew, seeking to gather allies, craft weapons, and fight the Primordials.
AT:O encompasses three gameplay modes: Strategic, Narrative, and Tactical. Exploration is a significant part of the game. In this stage, players gather resources and face random encounters. The first monster one has to deal with is the Hekatoncheir (100 hands). "When he's not busy fighting you, when you're in the battle but you're not keeping pressure on him, he starts tossing rocks at the Argo".*
Victory comes when you defeat the enemies or solve a crisis. You lose in a number of ways: if the Argonauts die, if the crew abandons you, if the ship is destroyed, if the enemies win, or if you run out of time.
There will be an early bird pledge for the first 24 hours, offering a mini for free. As for the availability of the game in stores later on, the designer says that it is not certain.
