Ahead of Ubisoft’s pre-E3 press conference, AusGamers had a chance to go hands-on with an early build of Assassin’s Creed Odyssey and writes:

“And the word options here is poignant. Because while traditional AC pillars remain in traversal, stealth, combat and more, theres a greater emphasis on decisive — and divisive — action. For example, a new option is Conquest Mode — here, the player tackles a new Nation Power system (given there are multiple nations you encounter throughout Ancient Greece and the Aegean Sea) where you work to sabotage and weaken a nations power (naturally), and when ready, based on decisions youve made through the earlier-mentioned conversation and choice combinations, you can enter Conquest Mode — a true 150 Vs 150 soldier battle where you also join the fight on the battlefield…”
