Every Flash game produced by Undefined
Back in early 2008 as a solo indie developer, I started producing flash games under the name Undefined. Over the subsequent years until the death of flash player I published 22 different free-to-play games, many of which were highly popular. Mostly as an answer to requests but also as a vanity project, I'm happy to present the entire collection.
If you remember any, it's most likely that it's one of the most popular game series, such as Protector or Legends of Arkandia, but, did you ever play the others?
With the advent of Ruffle, a new open-source flash player, I'm now able to bring those old games back to life and provide a standalone version of them.
Lots of work has gone into making sure each game runs at an acceptable level. There will be quirks, and sometimes things won't be exactly as they should be, but I have personally played every game in the pack and am happy with how they look and feel. The gameplay has been left mostly untouched, except where there were obvious bugs, which have been fixed.
I hope you enjoy playing this classic little slice of my brain, I've enjoyed putting the pack together and remember fondly creating each and every one.
This is where it all began. Back in 2008, tower defense was a simpler genre—Protector was my early attempt to mix tower defense with RPG depth. Over time, the series evolved, introducing faction rep, hero-specific units, equipment, skills, and even collectible Protectormons.
Here, the focus shifts to a sim-life experience. You manage your hero’s life—balance work, school, and the occasional dungeon crawl as you shape their destiny.
An evolution of the My Pet adventures, the Legends games refine the classic RPG formula with quirky, inventive gameplay. Expect unexpected twists that prove even old Flash games can break the mold.
These titles might not follow the series format, but they’re every bit as creative and fun. Each game has its own identity - a mix of experimental ideas, inventive mechanics. Whether you’re in the mood for bite-sized challenges or something off the beaten track, you’re in for a treat:
I've tested each game on the Deck and the majority run very well, some work is still needed for some games to improve performance, but overall, the experience is great. If you're having problems with a specific game, sometimes switching to Proton Experimental can improve performance.
