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?

“VOLTWOOD is deep, complete-feeling and extensively tested — but a competitive tower defense lives or dies on how it FEELS in thousands of real hands across thousands of maps, and that is the one thing testing alone cannot answer. Early Access lets us tune the difficulty curve, par calibration, onboarding, and readability against real players and real maps before we commit to 1.0. The game already ships with a built-in feedback line — Early Access is how we use it. If you like sinking your teeth into a systems-rich defense game and want a hand in shaping its balance and pacing, this is the time to jump in.”

Approximately how long will this game be in Early Access?

“Six months to a year. The point of Early Access for us is to get the balance right according to the people actually playing the game, and to close any gaps they identify. We consider Voltwood near content-complete today: our 1.0 gate is balance and polish validated by real players across a wide range of maps, not a feature count.”

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

“The full version is the finished, fully polished version of the game you are playing today — not a substantially different one. The core is all here: procedurally generated shareable maps, the par-based Torrent, the weekly roguelike Gauntlet and a casual mode, a deep roster of procedurally composed enemies and the fused weapon modules built to answer them, the multi-resource war economy, the Command Center, live leaderboards, and full localization in twelve languages. The road to 1.0 is polish and refinement within these systems, not new systems:
  • Difficulty and par calibration tuned from real Early Access play data across many maps
  • Onboarding and readability refined from first-time-player feedback
  • We are happy to add new content if the community wants it: like new enemy types, weapon modules, heroes and hero abilities shaped by player feedback. The systems are data-driven and built to grow if needed.
  • Presentation pass: visual evolution, late-game clarity, VFX polish
  • Quality-of-life and accessibility improvements the community asks for
We do not plan to gate existing content behind 1.0, and any price change at launch will be announced ahead of time.”

What is the current state of the Early Access version?

“Fully playable start to finish: the full enemy roster and every weapon module implemented, all modes live (Torrent, the weekly Gauntlet, casual), daily and weekly maps, the full economy and Command Center, per-map, personal and per-mode leaderboards, a first-run tutorial, a Field Manual, Steam achievements and Cloud saves, full controller support, and complete localization in twelve languages. The systems are stable and covered by an automated architecture test suite. What we're actively refining is the FEEL — difficulty tuning across the full range of maps, the clarity of the opening experience, and the visual polish a premium tower defense earns.

One expectation to set up front: balance patches change how a wave plays out, so they retire runs recorded on earlier builds. A saved replay from an older build can no longer be watched, a shared Solution from one can no longer be verified, and a score still waiting to upload when you update is dropped rather than posted. This does not touch your progress, your achievements or your Cloud saves. Expect it to keep happening while we are still tuning — it is the cost of the balance work Early Access is for.”

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

“The price may rise modestly at 1.0 as polish and content accrue. Any change will be announced in advance, so Early Access supporters always get the better deal.”

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

“We encourage the community to tell us about their experience by reporting bugs, suggesting changes and helping to shape the vision for how Voltwood can become the best it can be. Player feedback will be critical to delivering the 1.0 release of Voltwood.

Where we will talk to you, and what each channel is for
  • Dev updates — on this page and inside the game. Every build ships with written patch notes: posted to the Steam news feed, readable in-game under Patch Notes, and archived on our website. When a change came from a player report, the notes say so.
  • Talking to us — the Steam Community Hub. The discussion boards are the main room: strategy, balance argument and questions. This is the channel we check first.
  • Bugs and feature requests — the in-game feedback button. One click from anywhere in the game, and it attaches the map ID, wave and build version automatically, so we can reproduce exactly what you saw instead of guessing at it. The boards work fine for these too — the button is just the fastest route, not a rule.

How often
Every build we release ships with written notes — in the game, on the Steam news feed, and on our website. That is not just an intention: our build process will not produce a release that has no patch notes attached to it.

So you hear from us every time we ship a patch or a game update, and again whenever we reach a significant development milestone. When a change came from a player report, the notes say so.

What you can shape
The feedback we most need is about how the game balances:
  • Balance and par. Every battlefield is procedurally generated from a shareable map ID and scored against a par target, so "this map is unfair" is a report we can act on precisely: send us the map ID and we can regenerate the exact battlefield you played and retune against it. All balance in Voltwood lives in data catalogs rather than in code, so a well-argued report can move numbers in the next patch instead of the next milestone.
  • Modules against enemy types. Whether a weapon module actually answers the thing it is meant to answer, and which enemy compositions leave you with no good tool.
Beyond that, everything is open: enemy types and composition, module types, cards, champions, heroes and villains, the Gauntlet, leaderboards and scoring, map IDs, replays, onboarding and readability — and ideas for where the game should go next, including expansions. We would rather hear an idea than not.

We will not implement every suggestion, and we would rather say so than pretend otherwise. What we will do is consider each one properly, and tell you what we decided.

How we will run it
  • Every report gets a disposition. We keep a triage log of every bug and idea that reaches us, and each one is either fixed or answered with the reason it was not. Nothing is silently dropped.

About This Game

The map is never the same twice.

Every VOLTWOOD map is procedurally generated. The checkpoints, the resources, the blockers, the enemy types and amounts are a unique combination every time you play. If you want to replay or share a map, use its map ID.

You compete to maximize kills, not just kill the wave.

VOLTWOOD is a maze-building tower defense built to be competitive. Kill as many enemies as you can during each wave — and configure difficulty to boost your score for doing so. Building a good maze will help you kill more; building the best maze will earn you a spot on the leaderboard for that map.

Read your waves.

Enemies are data-driven compositions, creating unique blends of challenges. A deep roster of enemy types with real mechanics — phase shields, damage caps, splitters, mergers, frontal plows, air lanes, blink relays, self-repairing hulls, tower-jamming auras, an adaptive mirror, and bosses that fissure into fragments. View the wave composition in advance and plan your design to match it.

Survive each wave by meeting or exceeding par.

In the competitive modes, every wave has a calculated number of kills you must meet — its par. Kill enough, and you boost your Core's health. Kill too few and your Core loses health. Lose too much health and it's game over for that map.

Pick the right tower upgrade module for the job.

Kill more enemies by picking the right modules for your wave composition and map — upgrade modules layered over your tower's base barrel. Fuse them together to create unique merged effects. Choose wisely and you will be rewarded with more efficient kills.

Research unlocks and boosts.

A giant tech tree helps you focus on the most valuable unlocks and take advantage of global modifiers.

Resource scarcity adds depth.

Scarcity is part of the challenge. Power your buildings; mine, refine and trade for resources to advance your build. Resource availability and costs vary by map.

Oh, and your Command Center fights too.

Unlock Command Center modules with unique abilities: hypersonic missiles, drone swarms, stasis fields, hero barracks and more.

Dial up the challenge.

Difficulty settings let you raise the challenge — and your score — in competitive Torrent play. In casual mode, custom run options let you get creative and make the game easier or harder, to create the kind of experience that is the most fun for you.

Show off in the weekly Gauntlet.

After practicing solo in Torrent, show off your skills on the daily or weekly maps — or in the weekly Gauntlet, a unique sequence of maps to run through each week. Earn boons and coins that power your progression inside the run. Play for high score and rank on the Gauntlet leaderboard.
