About Undefined Game Pack

Undefined Game Pack - about the game
Relive the complete collection of 22 Flash games from indie developer Undefined, spanning tower defense, RPG, and strategy titles originally released from 2006 to the end of Flash. The pack revives classics like the Protector series, which blends tower defense with RPG elements such as faction reputation, hero units, equipment, skills, and collectible Protectormons, alongside My Pet Protector's life sim managing work, school, and dungeon crawls, and Legends of Arkandia's quirky RPG twists. Miscellaneous games deliver variety through space strategy across hundreds of levels in Engage, card-based play in Cardian, grid-based gem matching with RPG rules in Token Hero, and quick puzzle quests in Elements of Arkandia. Standalone versions run via Ruffle with bug fixes and tweaks for smooth play on PC, including solid Steam Deck performance-switch to Proton Experimental if needed. Gameplay stays true to originals, quirks included, for fans of bite-sized indie challenges and experimental mechanics.

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.

Games in This Pack
Protector Series

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.

  • Protector

  • Protector II

  • Protector III

  • Protector IV

  • Protector IV.V

My Pet Protector Series

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.

  • My Pet Protector

  • My Pet Protector II

  • My Pet Protector III

Legends Series

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.

  • Arkandian Crusade

  • Arkandian Revenant

  • Arkandian Explorer

Miscellaneous Gems

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:

  • Little Protectors – Mini Protector, 2d and includes several new ideas, some of which are good, some I hold my hands up and admit, not so good.

  • Hordes of Hordes – Another tower defense game, but one with a bunch of new ideas compared to Protector gameplay, such as dynamic pathing and endless gameplay.

  • Engage – A space strategy epic that spans 100s of levels.

  • Cardian – A card-based twist on classic gameplay elements.

  • Dead of Night – The very first Undefined game, it's still worth a few minutes of time.

  • Condor Cowboys – No comment.

  • Quick Quests – Heroic RPG goodness in 5-minute bursts.

  • Token Hero – Grid-based gem matching, but with its own rules and some RPG gameplay to boot. This was the last game I produced and includes a fitting tribute to my old best friend.

  • Elements of Arkandia – Puzzle quest, but with some Undefined magic and style.

  • Little Protector Planes – Session-based gameplay, pre-popularity of session-based gameplay. Explore infinite planes and recover treasures and powers from each one.

  • UO Defender - The prototype for Protecter, this small game was produced as a fan game for the game Ultima Online way back in 2006 before I really began producing games proper.

Steam Deck Support

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.
