The player takes on the role of Michael Travinsky, who doesn't remember a lot of things after the car accident. But the mysterious Lord of Light has a mission for him: to decide the fate of humanity. He also receives the ancient Sword of Light which is the most important weapon against evil. During the course of the game, he will visit three worlds (middle ages, the future of 2039 and the realm of darkness). Each world has its own set of characters and weapons.
Archangel is an action game with slight role-playing elements. Travinsky can explore the worlds freely, talk to other characters and take on various side quests. During fights, the focus of the game, he can either use a variety of standard weapons (melee and ranged) or special abilities (e.g. health regeneration, a shield or invisibility) which use up his spirit energy. This energy automatically refills over time, but is also required to use the powerful Sword of Light. He can also shapeshift into either a strong warrior or a sneaky ghost, but which one has to be chosen at the start of the game. Solving quests and killing enemies rewards experience points which are used to upgrade special abilities and the second form.
