The Action DOS Games That Changed Gaming Forever

[CharlesPalmere]

When people talk about the most influential games ever made, DOS games dominate the list in the action genre. The titles produced for MS-DOS in the early 1990s did not just push gaming forward — they redefined what was possible and set templates that developers are still using today. Playing them now is a direct encounter with gaming history.

Wolfenstein 3D — Where the FPS Began​

It is almost impossible to overstate the importance of Wolfenstein 3D to the first-person shooter genre. Released in 1992 by id Software, it took the concept of navigating a three-dimensional environment from a first-person perspective and turned it into something commercially viable and genuinely thrilling. You played as B.J. Blazkowicz escaping from a Nazi prison castle, fighting guards and eventually a mechanized final boss.

By the standards of DOS games of its era, the graphics were revolutionary. The speed of movement felt visceral. The shooting was immediately satisfying. The formula that Wolfenstein 3D established — fast movement, weapon pickups, enemy variety, level-based progression — is still the backbone of virtually every FPS made today.

DOOM — The Game That Defined a Decade​

DOOM arrived in 1993 and took everything Wolfenstein 3D had established and amplified it. More complex level design. More enemy variety. Multiplayer deathmatches. Modding support that turned the game into a platform for user creativity. DOOM became a cultural phenomenon as well as a game, and it remained relevant long enough to spawn sequels, revivals, and enduring mods like Brutal DOOM.

As DOS Games go, DOOM is perhaps the most important single title ever released on the platform. Playing it today, the pacing and design still hold up. The levels feel purposeful. The enemies have distinct behaviors that demand different approaches. The weapon progression is satisfying.

Commander Keen — Platform Games Find Their Footing on PC​

Before Commander Keen, the conventional wisdom was that smooth-scrolling platform games were impossible on PC hardware. DOS games were supposed to be limited to flickery, jerky movement that could not match the fluidity of console titles. Commander Keen proved that assumption wrong.

id Software's earlier series used adaptive tile refresh technology to achieve smooth horizontal scrolling, and the result felt like a revelation. Suddenly the PC could do what Nintendo was doing, and dos games would never be the same. Commander Keen 4, in particular, remains a genuinely enjoyable platformer with clever level design and a distinctive personality.

Brutal DOOM — A Modern Take on a DOS Classic​

Brutal DOOM is an interesting case — technically a modification of the original DOOM engine rather than an original DOS game, but worth mentioning because it demonstrates the enduring power of the platform. The modification dramatically expanded the violence and intensity of the original game while preserving the fundamental design. It remains one of the most-played DOOM experiences available today.

Conclusion​

The action DOS games of the early 1990s did not just entertain a generation — they invented the first-person shooter genre, proved that PC hardware could match consoles for platforming, and established design principles that still define modern games. Every one of these titles is available free in a browser today, exactly as they played in their original era. If you have never fired up Wolfenstein 3D or Commander Keen, you are missing a piece of gaming history.
