A tactical action game where you defeat approaching enemy forces with a massive army. Set in an alternate dimension created by the suddenly appearing Demon Lord Orochi, this game depicts the fierce battles of heroes from both the "Dynasty Warriors" and "Samurai Warriors" series. Some join Orochi's forces, while others aim to defeat them... "What will the outcome be in the battle of wits between Zhuge Liang and Takeda Shingen?" "What if Cao Cao and Oda Nobunaga met?" Breaking down the boundaries of the series, heroes gather in different dimensions, creating a more dynamic and dramatic story than ever before. Improve your team's fighting power by fusing weapons, acquiring character-specific items, and mastering each character's special skills.
