First‑person shooters have dominated gaming for over three decades — evolving from niche PC shooters to console blockbusters and annual juggernauts. Some franchises released a handful of games and faded. Others delivered sequel after sequel across hardware generations.

This list ranks the Top 10 FPS franchises with the most mainline games, using Option A rules: strict mainline entries only, no remasters counted as new games, and no spin‑offs or multiplayer‑only releases. It’s a reverse countdown, from #10 to the most prolific FPS franchise of all time.

10. Metro

Total Mainline Games: 3
Most Recent Release: Metro Exodus (2019)

The Metro trilogy is a standout in survival‑heavy FPS design, weaving immersive storytelling with limited ammo and a haunting post‑apocalyptic Russia. Its consistency over three solid entries earns it a place on this list despite a lower count.

9. Killzone

Total Mainline Games: 6
Most Recent Release: Killzone Shadow Fall (2013)

Sony’s premier shooter franchise on PlayStation carved out a brutal sci‑fi identity in competition with big names like Halo. Six mainline campaigns helped define early PlayStation FPS expectations.

8. Wolfenstein

Total Mainline Games: 6
Most Recent Release: Wolfenstein II: The New Colossus (2017)

One of the genre’s earliest pillars, Wolfenstein has six major mainline entries (from legacy classics through modern reboot campaigns). A new sequel (Wolfenstein III) is reported to be in development, though no release date has been confirmed yet.

7. DOOM

Total Mainline Games: 8
Most Recent Release: DOOM: The Dark Ages (2025)

The Doom franchise helped define what FPS meant in the first place. DOOM: The Dark Ages — released on May 15, 2025 — is the latest mainline entry, expanding the series’ mythos with medieval settings and new combat twists.

6. Far Cry

Total Mainline Games: 6
Most Recent Release: Far Cry 6 (2021)

Ubisoft’s open‑world FPS staple dropped players into hostile regions with memorable antagonists across six core entries. Though the formula sometimes feels familiar, its consistency and global success keep it in the elite of long‑running FPS franchises.

5. Halo

Total Mainline Games: 6
Most Recent Release: Halo Infinite (2021)

Few shooters define a console generation like Halo. Its six mainline campaigns have influenced FPS controls, multiplayer dynamics, and narrative design on consoles, even as spin‑offs and expanded content bloomed around them.

4. Battlefield

Total Mainline Games: 12
Most Recent Release: Battlefield 6 (2025)

EA’s sprawling military shooter series is built on large‑scale warfare, destructible environments, and vehicular combat. Battlefield 6 — released in 2025 — set new sales records for the franchise, underscoring its longevity.

3. Tom Clancy’s Rainbow Six

Total Mainline Games: 13
Most Recent Release: Tom Clancy’s Rainbow Six Siege (2015)

Originally rooted in tactical realism, Rainbow Six evolved into one of the most enduring tactical shooters. Every mainline game helped refine precision‑focused combat and team‑oriented design, and Siege’s ongoing support has kept it relevant long after release.

2. Medal of Honor

Total Mainline Games: 14
Most Recent Release: Medal of Honor: Above and Beyond (2020)

Before Call of Duty’s dominance, Medal of Honor defined cinematic military shooters. Its 14 core FPS titles span from PS1 launches to modern standalone campaigns, cementing its legacy in military gaming history.

1. Call of Duty

Total Mainline Games: 20+
Most Recent Release: Call of Duty: Black Ops 7 (2025)

Ranking by pure mainline output shows just how prolific some FPS franchises have become — from the storytelling depth of Metro to the genre dominance of Call of Duty.
By sticking to core releases only, this list avoids inflated counts while highlighting the true giants of shooter gaming.
