We get asked constantly where to start with DOS gaming, so here’s an honest answer instead of a generic “best of” list: ten shareware episodes we’d actually hand a first-timer, picked for being free to download, running well in DOSBox, and holding up as genuinely good games rather than just historically important ones. A few are here because they’re essential history you should know regardless of taste; most are here because they’re still fun on their own merits.
A quick note on how we picked these: every game below is legally free, either an official shareware episode or a full freeware release, so you won’t hit a paywall or a broken download link partway through. We’ve also tried to spread the list across genres rather than stacking it with shooters, if you’ve never touched a DOS-era shooter before, start with Wolfenstein 3D rather than jumping straight into Quake; the jump in complexity between them is bigger than you’d expect.
1. Doom (1993) — Still the Benchmark
If you only play one DOS game in your life, make it Doom. id Software’s shooter is fast, atmospheric, and still endlessly replayable three decades on. The shareware episode, nine full levels, is free and gives you a complete taste of one of gaming history’s most important works; if the sprite-based visuals feel dated at first, give it twenty minutes, the level design and pacing rarely do.

2. Wolfenstein 3D (1992) — Where the Genre Actually Started
Before Doom, id Software created the first-person shooter genre with Wolfenstein 3D. Fight through Castle Wolfenstein, blast Nazi soldiers, and take down Mecha-Hitler across three free shareware episodes. It’s simpler and more repetitive than what came after, flat corridors, no verticality, but that simplicity is exactly why it’s worth playing: you can feel the entire genre’s starting point in a single sitting.

3. Quake (1996) — The Jump to True 3D
Quake moved beyond sprites and fake depth to deliver fully 3D environments and enemies, a genuine revolution at the time. The dark, Lovecraftian atmosphere and Trent Reznor’s ambient soundtrack make it uniquely compelling even next to its own sequels. The free shareware episode holds up brilliantly, and the movement tech it introduced (strafe-jumping, rocket-jumping) still shapes how competitive shooters play today. Download Quake →
4. Duke Nukem 3D (1996) — The Most Interactive Shooter of Its Era
Duke Nukem 3D blew minds in 1996 with its interactive environments, one-liners, and sheer variety. Flush toilets, flip light switches, blow up walls, then blast aliens with a shrink ray. The shareware episode is a self-contained blast, and it’s the game that best captures how much personality a DOS shooter could have once the technology caught up to the ambition.

5. Heretic (1994) — Doom in a Dark Fantasy World
What if Doom took place in a brooding medieval fantasy setting instead of a space station? Heretic answers that question with real elegance. Built on a modified Doom engine, it adds inventory items, new enemy types, and an atmosphere that stands apart from everything else in the genre at the time, it’s a genuinely underrated entry point if you’ve already burned through Doom. Download Heretic →
6. Jazz Jackrabbit (1994) — DOS Gets Its Own Sonic
Epic MegaGames built a high-speed platformer that matched the energy and color of Sega’s Sonic the Hedgehog, and on period-appropriate hardware it genuinely competed with consoles on smoothness. Jazz Jackrabbit is joyful, fast, and bursting with personality, a good pick if you want to show someone that DOS wasn’t only shooters and adventure games. Download Jazz Jackrabbit →
7. Hexen: Beyond Heretic (1995) — For When Heretic Isn’t Enough
If you loved Heretic and want something deeper, Hexen offers three character classes, hub-based level design, and puzzle-solving that no other DOS shooter of the era attempted. It’s demanding and occasionally obtuse about what it wants from you, but the hub structure was genuinely ahead of its time and still feels distinct from anything else on this list. Download Hexen →
8. Raptor: Call of the Shadows (1994) — The Best DOS Shmup
Vertical scrolling shooters were an arcade staple, and Raptor is the finest the DOS world produced. The upgrade system, spend earnings between levels on new weapons and shields, gives it a strategic layer that pure arcade shmups lack, so runs actually build on each other instead of resetting your options every mission. Download Raptor →
9. Blake Stone: Aliens of Gold (1993) — The One Everyone Forgot
Released just days before Doom, Blake Stone never got the recognition it deserved, mostly a matter of catastrophically bad timing. A spy-themed shooter with smarter level design than Wolfenstein 3D, it features informants who give you tips, multiple weapon upgrades, and six episodes of content. The free shareware version covers the first two episodes, and it’s worth playing specifically to see what Wolfenstein-era design looked like right before Doom made it obsolete overnight. Download Blake Stone →
10. Cosmo’s Cosmic Adventure (1992) — The Pick for Non-Shooter Fans
Not every great DOS game is a shooter. Cosmo’s Cosmic Adventure is a charming platformer starring an alien child with suction-cup hands who can climb walls and ceilings. It’s colorful, creative, and genuinely fun for players of any age, and it’s our go-to recommendation for introducing someone to DOS gaming who has no interest in shooting anything at all. The first episode is free. Download Cosmo →
A Quick Word on Actually Getting These Running
Every game above needs DOSBox to run on a modern PC, and none of them need more than about ten minutes of setup once you know what you’re doing. Our complete DOSBox installation guide walks through the whole process on Windows, Mac, or Linux, and covers the handful of settings (CPU cycles, sound card setup) that actually matter for getting these specific games running smoothly rather than just technically launching.
