10 Free Unique Browser Games!

1) Kingdom of Loathing

One part text based, one part drawn on MS paint. Kingdom of Loathing is an rpg that I'm not even going to try to explain. If you think this is up your alley, it probably is. At least stick it out past the tutorial and get a taste of the game, this one is definitely worth checking out.

2) A Dark Room

I'm going to quote the source I used to find this game, reddit user Kintaro08 "I was absolutely addicted to A Dark Room. Don't look up any FAQs or hints or anything. Just roll with it and discover every part of the game yourself. It's a unique gaming experience you can only do once."

He is not wrong. http://adarkroom.doublespeakgames.com/

Someone else recommended using this at the same time. Also not wrong. http://www.rainymood.com/

3) SUPER. HOT. SUPER. HOT. SUPER. HOT.

TIME MOVES ONLY WHEN YOU MOVE. Now a fully fledged game available for purchase, if you haven't played this yet do yourself a favor and check out the original prototype which is still available on browser. Worth noting this one requires Unity (I know, ugh, worth it though). http://superhotgame.com/

Does anyone recognise this footage?

4) SUPERHOTline Miami

You guessed it, all the slowmowyness of SUPERHOT combined with the top downyness of Hotline Miami. If you enjoy these things you're in luck because there's a full game as well called SHOOTOUT Inc.

SHOOTOUT Inc.

This one isn't browser based, but it's the full game based on SUPERHOTline Miami so I thought I'd include it. It's 70mb, available for download here. https://albatr.itch.io/shootout-inc

5) Contre Jour

An atmospheric physics based puzzle game. Move by manipulating the environment around you. Tbh I'm not a fan of most of these in-browser physics based platformers, but this one kept my attention longer than most. Almost definitely better while stoned.

6) Parameters

A unique rpg stripped down to just numbers. Black squares are quests, yellow squares are bosses. Surprisingly satisfying.

10) Fallen London

"A browser-based choose-your-own-adventure game set in "Fallen London", an alternative Victorian London with gothic overtones."

Basically like living inside the world of a penny dreadful. I absolutely adore this game for what it tries to be, I only wish it didn't utilize the adventure point system so I could play it in longer increments.
