Firewall Zero Hour is not online-only. It is a virtual reality (VR) game developed exclusively for the PlayStation VR (PSVR) headset. However, an internet connection is required to play the game.
Firewall Zero Hour is a team-based multiplayer shooter game that focuses on tactical gameplay and strategy. In order to fully enjoy the game, you will need to connect to the internet to play with and against other players online. The game features different multiplayer modes, such as Training and Contract modes, where you can team up with other players or compete against them.
While an internet connection is required to play Firewall Zero Hour, it is important to note that PlayStation Plus (PS Plus) subscription is only required for certain multiplayer modes. PS Plus is a paid subscription service provided by Sony for PlayStation users, which offers various benefits including online multiplayer access, free monthly games, and exclusive discounts.
If you have a PS Plus subscription, you will be able to access additional features and benefits in Firewall Zero Hour, such as Multiplayer Training and Multiplayer Contract modes. These modes allow you to train with other players or participate in contracts and missions as a team.
However, it is worth mentioning that even without a PS Plus subscription, you can still enjoy the game by playing the single-player mode or utilizing the offline features.
In my personal experience, I have played Firewall Zero Hour both with and without a PS Plus subscription. While playing with a PS Plus subscription added the element of online multiplayer and the ability to team up with other players, playing the single-player mode or offline features still provided an enjoyable experience.
To summarize, an internet connection is required to play Firewall Zero Hour, but a PS Plus subscription is only necessary for certain multiplayer modes. The game offers a variety of gameplay options, both online and offline, allowing players to choose their preferred mode of play.
