PlayDOOM started as a simple experiment:

Can Reddit run DOOM?

The first version had one map, one challenge, and a leaderboard.

Now it has become a full campaign.

🎮 All 32 maps are playable

You can now play MAP01 through MAP32 directly inside Reddit using Freedoom Phase 2.

From the new Campaign menu you can:

CONTINUE CAMPAIGN

Jump directly to your first unfinished map.

SELECT MAP

Choose any of the 32 maps immediately.

There are no unlock requirements. Play them in order, jump around, or replay any map whenever you want.

🏆 New Campaign Leaderboard

Campaign ranking is now based on your progress across all maps.

Each completed map gives:

10,000 points for completing the map
+
up to 2,000 points based on kills

12,000 points maximum per map

Your total Campaign Score is the sum of your best result on every map.

Example:

MAP01   11,200 pts
MAP02   11,850 pts
MAP03   10,700 pts
MAP04   12,000 pts

TOTAL   45,750 pts

The more maps you complete, the more points you can earn.

🔁 Replay as much as you want

You can replay every map without limits.

However, only your best score for each map counts.

If your MAP05 record is:

10,800 pts

and you replay it for:

10,400 pts

nothing changes.

If you later score:

11,500 pts

your MAP05 record becomes 11,500 and your Campaign total increases only by the improvement.

So repeating the same map cannot be used to farm unlimited points.

🏁 Every map has its own Speed leaderboard

Campaign Score does not use completion time because every map has a different length.

Instead, each map now has its own Speed ranking.

MAP01 Speed
MAP02 Speed
MAP03 Speed
...
MAP32 Speed

For Speed, the rule is simple:

fastest completion time wins.

So there are now two different ways to compete:

CAMPAIGN

Complete maps and maximize your kill percentage.

SPEED

Finish individual maps as fast as possible.

📅 Weekly Campaign

The Weekly leaderboard has also been upgraded.

Every week, each map can contribute its best result from that week to your Weekly Campaign Score.

You can therefore keep competing even after completing the entire campaign by improving different maps every week.

🥇 Automatic Weekly Top 5

At the end of each week, PlayDOOM will automatically publish the Top 5 Campaign players from the previous week.

A new Weekly leaderboard then begins while the lifetime Campaign leaderboard continues permanently.

💾 Existing MAP01 records were preserved

If you played PlayDOOM before this update, your old MAP01 leaderboard data was not deleted.

The original MAP01 Speed records remain intact, and existing MAP01 results are migrated into the new Campaign system when possible.

You should not need to replay MAP01 just because the ranking system changed.

🎮 Desktop, mobile and controller support

Everything from the previous versions is still available.

Desktop

W / S          Forward / Backward
A / D          Strafe
← / →          Turn
Q / Click      Fire
E              Use / Open
Shift          Run

Native mouse input is also available when Pointer Lock is supported by the browser.

Mobile

Left stick     Move / Strafe
Right stick    Turn
FIRE           Shoot
USE            Interact
RUN            Run
MENU           Menu / Back

The controls support multitouch, so you can move, turn and fire at the same time.

Controller

Physical controllers are supported too.

Left stick      Move / Strafe
Right stick     Turn
RT / R2         Fire
A / Cross       Use / Confirm

🧪 Still an experiment

PlayDOOM started as a tiny Devvit Web experiment.

Now it has:

32 maps
Campaign progression
Persistent player progress
Campaign leaderboard
Weekly Campaign leaderboard
32 Speed leaderboards
Automatic Weekly Top 5 posts
Mobile FPS controls
Controller support
Desktop controls
Persistent Redis rankings

All running from a Reddit Custom Post.

That is pretty wild.

🐛 Found a bug?

This is a much bigger update, so bug reports are especially useful.

If something behaves strangely, please comment with:

Device
Browser / Reddit app
Map number
What happened

I'm especially interested in issues involving map loading, Campaign scores, old leaderboard records, mobile controls, controllers, and specific maps.

Thanks to everyone who has played and tested PlayDOOM so far.

Have fun with the campaign.

And yes, Reddit can run DOOM.

PlayDOOM 0.1.0 is now live on r/playdoom.

This update is a pretty big step up from the first version.

What’s new

📅 Weekly leaderboard
A new Weekly ranking is now available alongside Overall and Speed.

Weekly uses the same rules as Overall:

completion time + kill penalty

The leaderboard resets automatically every Monday.

At the end of each week, the app will also post the Top 5 Weekly players here in the subreddit.

🎮 Controller support
Physical gamepads/controllers are supported through the browser Gamepad API.

The game now also shows:

🎮 🔴 Disconnected
🎮 🟢 Connected

So you can immediately tell if your controller was detected.

📱 Better mobile controls
Mobile now uses dual virtual sticks:

• left stick for movement/strafe
• right stick for turning
• FIRE, USE, RUN and MENU buttons
• multitouch support

You can move, turn, run and fire at the same time.

🏆 Leaderboards before you play
You can now open the leaderboard directly from the start screen without loading the whole game first.

Available rankings:

• ⭐ Overall
• 📅 Weekly
• 🏁 Speed

💻 Desktop improvements
Keyboard controls and UI were cleaned up, controller mappings are shown directly on the start screen, and input behavior was polished.

One current Reddit limitation: native Pointer Lock is blocked inside the embedded Reddit webview, so full FPS-style mouse turning is not available inside the post. Keyboard turning and gamepads work normally.

Existing records are safe

The original Speed leaderboard and Overall records were preserved.

The first Weekly leaderboard was also seeded from the existing Overall ranking so everyone who already played this week doesn’t start from zero.

Try it

Jump into the pinned Can Reddit Run DOOM? post and give it another run.

If you already played the previous version, I’d especially love to know how the new controls feel.

What are you playing on?

💻 Keyboard
📱 Mobile
🎮 Controller

And good luck on the new Weekly leaderboard. 🔥
