About Incursion

Incursion is a first-person wave-survival shooter for solo play or online co-op. As a soldier in the Republic Defense Force (RDF), you clear infected from strategic locations and defend high-value areas after an alien civilization unleashes an infectious virus on Earth in an event known as The Incursion. Matches last 15–40 minutes, and the game offers an estimated 2–4 hours of gameplay.

Combat and modes

You fight waves of enemies across different game modes, from dodging enemies in an alley to defending a single point. Combat is reflex-based, and you can build defenses while working toward alternative weapons.

You can play alone or fight online alongside friends or strangers. In co-op, class choices, perks and weapons shape how you approach each match; in singleplayer, you take on the job by yourself.

Classes and loadouts

Classes grant abilities that can help you clear groups of enemies or escape more quickly. You can equip any weapon in any weapon slot, allowing you to combine weapons to suit different ranges and approaches.

Perks and progression

You level up in-game through a reforged perk system. Perks can increase damage or running speed, or change your starting weapons. Some make the game harder by lowering your health, resetting your money in multiplayer or applying other debuffs.

The perk system also lets you choose your in-game level. You can use lower-level perks when playing with someone new, or max out your perks to take on the hardest difficulties.
