Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“I've put a lot of time into testing to make sure everything works as it should, but that testing has primarily been only on my end. I'm unsure how my game will perform across a wider range of hardware. That's why it's in Early Access, so I can gather feedback from more people and make sure everything is running as smoothly as possible.”

Approximately how long will this game be in Early Access?

“My goal is no longer than 6 months. Ideally I'd like to get my game out of early access as soon as possible. Though, that time frame depends on how much feedback I receive and what's all involved with working on an update to patch it.”

How is the full version planned to differ from the Early Access version?

“IronFire Idle Defense is a feature rich game as is. Though, there are some other ideas I have that I plan to revisit in the future to introduce new mechanics for zombies and so you can take your builds even further.”

What is the current state of the Early Access version?

“The game is playable from start to finish. Optionally, after finishing the main progression, you can proceed into endless days. There could be some lingering bugs that have yet to be discovered but so far progression has been smooth.”

Will the game be priced differently during and after Early Access?

“I'm a solo dev who's self funding everything. That being said, my game will be cheaper while in early access and might slightly increase when out of early access.”

How are you planning on involving the Community in your development process?

“Being a gamer myself for most of my life, I've learned that listening to the community for feedback is what helps improve the game, whether that feedback is good or bad.

I would really like to eventually do polls on Discord for any potential changes that might be wanted or feature suggestions. Potential bug reports, preferably have a community support section, share your builds, share strategies, show off your unlocked skins, etc.

(the discord invite to the official IronFire Idle Defense server is on this page and in-game found in the Data Center).”

- Clear day 1,500 to access horde mode for faster spawns and continued progression into endless waves.

and more!

HEAVY AND CHILL PLAYLISTS EXPLAINED:

There are over 10 songs per-playlist and the idea is to choose one song you like and loop it but songs will play through if you choose not to, up to you. The heavy playlist has songs more consistent with guitars, bass, drums and harder-hitting beats. The chill playlist has songs more consistent with synths, piano, drums and lighter-hitting beats. Some songs use elements from both styles, but tracks are placed based on the overall feel of the song.

BOSS SPAWNS EXPLAINED:

Bosses have a lower spawn chance from days 10 through 360. For days 370+ though, bosses have a much higher spawn chance. This is due to the fact of there being so many build variations, I did not want someone being blocked from progressing if they're not strong enough to defeat one of the bosses early on but I also want bosses to feel like their role is used properly, so that's why later in the game bosses will spawn more consistently.

NOTE FROM THE DEV:

I enjoy playing defense, roguelite and idle games; this is my take on what those are like when combined. From days 1 through 99, waves are less dense than days 100+. 

I like games with lots of upgrade options, massive build depth and silly content to discover in what appears to be an otherwise serious game; I believe I delivered on those. I did my best to balance it, putting countless time into testing. Though, I am open to make changes depending on feedback.

Some of the music used was created by my brother and uncle when they were younger. I created the sound effects and rest of the music using music production software; it's all original and no ai was used. One of my cousins helped with some of the artwork and I tried to make content look as good as I could (I think it turned out alright). I hope you enjoy playing and I'm looking forward to seeing your builds!
