Obsidian Catalyst is a huge love letter to the old Shining Force games on the Mega Drive/Genesis and Saturn from the 90s and aims to mimic the style of those games a great deal. The SF games are tactics RPGs where you control a squad of up to twelve units and move them around a grid to attack enemies. It's functionally quite similar to the Fire Emblem series which is likely more familiar to people than the old SF games!

I have taken the basic formula of these games and made my own additions to make combat feel dynamic and satisfying. Characters all learn special attacks that are mostly unique to their classes and allow them to attack enemies in interesting ways. Each class has its own strengths and weaknesses and learning how to best utilise them in combat should feel extremely rewarding. Currently there are sixteen playable characters (and the maximum squad size is twelve) however no character should feel like a dud - my endgame is that all characters should be viable and it should be up to the player to field a squad of their favourite units!

The overarching theme and plot of the game and the villains (more on that in the storyline section below) are written as serious and credible but overall I intend for the game to have a lighthearted tone but be serious when it needs to be - this gives me the opportunity to make a few nods at the inspiration behind the game! Currently the prologue and the first four chapters of the game are complete; tentatively this gives the game a runtime of around 15 hours for a first playthrough thus far.

Below is a small selection of some of the games maps!

Sicherheim Slums District Three

Sicherheim Northern Forest

Zaros Village

Port City of Hafenstadt

Mount Marigosa Caves

Iridesh Castle Catacombs

Mount Uran Trail

Mittelstadt West Hills

Town of Ebenendorf

  • Eremar, the Swordsman
    The player character and jack of all trades. The strong and silent type! Fights with swords.
  • Melanie, the Lancer
    An outspoken and athletic girl with a fiery demeanour. Quick to leap into action and cares about her friends and family. Fights with lances and glaives.
  • Dereck, the Warrior
    A young man whos pleasant attitude offsets his rough exterior. Fights with axes.
  • Victor, the Archer
    An easily spooked young man that prefers to take things easy. Fights with bows and crossbows.
  • Theodore, the Cleric
    A softly spoken and studious young man. Enjoys a good book. Fights with staves and wands.
  • Anne, the Mage
    A rather blunt girl with a knack for magic. Fights with staves and wands.


  • Our story is set in the world of Lossock. In the sleepy, countryside town of Vinheim in the South of the country of Rilinth, Eremar and his friends spend their days enjoying each others company and
    exploring the nearby countryside. One evening one of their group spies a strange phenomenon occuring in the forest near the village and so the following morning they head out to explore the forest and delve deep into some ruins. Inside the ruins there is a strange interaction with a magical keepsake and so the group decide to seek the wisdom of their elders to learn more. Upon returning to Vinheim they find that the village has been raided by soldiers from the capital city of Sicherheim, the town all but destroyed and the men taken prisoner. The group steal themselves away in the middle of the night unbeknowest to the rest of the townfolk with the intent of doing the impossible: breaking into Sicherheim, locating the men of the village and rescuing them to safety.

    Along the way they find themselves embroiled in a much larger plot and that the fate of the whole world hangs in the balance. The Sicherheim army is poised to strike and it is likely that none of the world's other nations would understand their true intentions or really be prepared to stand in their way. Thus begins their journey around the world of Lossock, a race against time against the overwhelmingly superior forces of the Sicherheim army to uncover the myths and legends of the Obsidian Catalyst.

I played your game and found the tactics system pretty neat but with a few points of improvement.

Hi! Thank you for taking the time to give the game a try!

First thing: the bedside table there is the event I use to teleport to maps to test them from a new build and I can't believe I forgot to remove it! That will be patched in the download link above probably by the time you're reading this!

A few other notes based on your video:

When I started the project it began as a solely RTP project as I learned how to use the plugin and the prologue chapter was developed pretty quickly as a proof of concept of sorts. Tt's grown into something quite a bit bigger since then as I've continued to work on it and I definitely agree that I should update Vinheim Town and probably the first forest map to use some of the tilesets that I've picked up since! I was planning to do that with the next major update which will add in chapter 5 as well as the promotion system.

Currently direction facing doesn't matter for dealing damage (like in Shining Force), but I also agree that it would be nice to be able to choose direction at the end of a turn even if it's a purely visual effect - I can ask in the forum thread where the plugin is developed how feasible that would be!

The mage character joins the party after this battle following a cutscene event - my intent was that this first fight is essentially a tutorial to learn the combat system, and that in future fights I add in more people and mechanics.

The reason you couldn't move around the spider on the bridge is that enemies and player characters exert a zone of control which heavily restricts movement around opposing forces - I think I could improve the first battle massively by adding in a tutorial to explain the game mechanics.

A big thing I took away from your video was that you expected it to be more like FFT than Fire Emblem - I have no plans really to change it to an on-map battle system as this doesn't go with the FE/SF style of gameplay that I'm imitating. Not that I think FFT isn't good - it's just not what I'm going for here and honestly Fell Seal absolutely nailed the FFT style SRPG.

I'm glad that you thought it was neat though, honestly thank you so much for taking the time to not only play it and give me your thoughts but to do it in a youtube video!

A beloved family member passed away due to complication to combat COVID and diabetes. Rest in peace Grandma.
Just got FES pack for my MZ. The details of the tilesets and chars seem not very compatible with MZ rtp. Look like they are scaled up. Not saying it's bad, but just won't fit well.
I've been busy with other things lately but I'm getting back into working on stuff for my game next month. I think I'm going to fiddle with making NPC busts next, mixing and matching stuff from DLC I've purchased.
Just finished composing a boss battle theme!
