About Fortified

Fortified thrusts players into a 1950s‑styled sci‑fi setting where Earth confronts a relentless Martian invasion. The game fuses third‑person shooting, real‑time strategy, and tower‑defense mechanics, letting you both fire Cold War‑era weapons and direct defensive structures.

Choose from four pulp‑inspired heroes and defend the city solo or with up to three friends. Team coordination is highlighted, as victory “only comes to those who work together,” making co‑op play a central experience.

01 / THE GUIDE

Gameplay Mechanics

Fortified blends third‑person shooter action with real‑time strategy and tower‑defense systems. Players wield Cold War‑era weapons while simultaneously placing defensive structures to stop waves of robot invaders, creating a constant shift between direct combat and strategic planning.

The hybrid design is described as “Genre‑Bending Gameplay,” emphasizing that the combination of these three genres forms the core loop of the game and defines how each encounter unfolds.

  • Switch between shooting and building as enemy waves approach.
  • Observe enemy patterns to decide when to prioritize firepower or construction.

02 / THE GUIDE

Character Classes

Four distinct classes draw from classic pulp archetypes: a jetpack‑piloting heroine, a shotgun‑wielding space cowboy, a secret government agent, and a battle‑hardened Marine captain. Each class provides its own weapon set and movement style, shaping how you engage enemies and build defenses.

The description notes that these classes are “Pulp Inspired,” meaning their abilities reflect the narrative roles they represent, giving players varied approaches to the same defensive challenges.

  • Select the jetpack hero for rapid repositioning across the battlefield.
  • Use the Marine captain when sustained firepower is needed.

Co‑op Mode

Fortified supports up to four players in cooperative play, allowing teammates to share defensive duties and combine firepower. The co‑op experience stresses coordination, as the game states “victory only comes to those who work together.”

Co‑op matches let each player focus on a specific role—building, shooting, or supporting—making teamwork essential for surviving the Martian machine waves.

  • Communicate building zones to avoid overlapping structures.
  • Synchronize attacks when a large wave appears.

04 / THE GUIDE

Defensive Building

Players fortify their base by constructing a network of defensive structures. Placement is strategic, requiring coverage of multiple approach vectors so that robot invaders are halted before reaching the city core.

The game emphasizes that building a “network of defensive structures” is essential for turning the tide against increasingly intense enemy waves.

  • Place towers at choke points to maximize coverage.
  • Consider spacing structures to create overlapping fields of fire.

Platform Features

Fortified runs on Windows and includes full controller support, Steam achievements, Steam Cloud saves, Remote Play on TV, Family Sharing, and Steam Trading Cards. These features integrate the title into the Steam ecosystem for flexible play options.

The presence of “Full controller support” and “Remote Play on TV” indicates that the game can be enjoyed with a gamepad on a television, while Cloud saves preserve progress across multiple PCs.

  • Enable Steam Cloud to keep your progress synced across devices.
  • Use Remote Play on TV for a couch‑co‑op experience.
