the stick in the direction of the target with follow-up stick movements applying further attacks with projectile attacks only using an auto lock-on system. Attacks can be combined to execute attacks such as performing combos on enemies in mid-air, attack slides, and juggling foes in the air with projectile weapon attacks. Another aspect of combat are "Ruiner" attacks, powerful abilities that can indirectly affect surrounding enemies and can be mixed with other attacks to perform finishing strikes. The role-playing elements of the game come in the form of advanced character customization. At the beginning of the game, the player is given the choice between five different classes; berserker, champion, defender, commando, and bio engineer, with each having an advantage over another. The berserker is focused on melee combat while the commando is oriented on ranged combat. The bio engineer has advanced healing abilities and the defender has a strong armor defense. Finally, the champion is a balanced all rounder with multiple air strike attacks. During the game, players can collect various items that they can equip and use. There are fifteen variations of weapon classes such as pistols, heavy lasers, dual and two-handed combat weapons, armor for different body parts, and "charms" that allow players to use powerful Ruiner abilities. Many items can also be bought and customized by color and effectiveness—using collectable runes—in-between levels back at the Æsir's base of Asgard. As players progress through the game, they can level up by slaying foes (Goblins, Trolls, Dark Elves, and Undead) and achieving high combos, allowing access to more efficient items and skills; these items and skills can be used in the game's skill tree mechanic, where points earned with every level up are applied to improve stats and unlock new abilities unique to each different character class. In the early stages of the game, the player can choose between two alignments; Cybernetic and Human. The Cybernetic alignment allows use of certain weapons like heavy lasers and further cybernetic upgrades, while the Human alignment emphasizes quick movement and improved combos.

Hosts can support only a second player with a "drop-in, drop out" system. This allows players to join games hosted in levels they have yet to complete, as long as the host has, allowing high and low-level
