Firewall: Zero Hour

Firewall: Zero Hour is an online, or offline via training, virtual reality tactical action shooter where players called contractors take on contracts issued from agents who are known as mother and father. Each contractor has a different passive skill for use on the field which can help support the player fend off the enemy team from completing their objective. There are 12 contractors players can choose from all with a set primary skill and a secondary skill you can edit. Weapon loadouts are also customizable where players can pick a primary weapon, secondary weapon, one lethal equipment and one nonlethal equipment. Taking on contracts players will receive experience for certain actions they complete, as well as earning in-game currency known as "Crypto" where both can be found scattered around the map or completing the contract.

Players can practice their tactics against AI enemies that scale with rank either solo, or in a 4-player squad which either can be private or public matchmaking.

Initial reviews for Firewall: Zero Hour were positive and the game was praised as being a major step forward for virtual reality gaming.
