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?

“Terrors of War is an ambitious alternate history WW2 RTS being built by a solo developer. The core combat, economy and superweapon systems already work in single player skirmishes and handcrafted Operations, but the full story campaign and later systems need more time and iteration.

Early Access lets you help decide what happens next. Your feedback can steer balance changes, new Operations and the shape of the 1944 to 1957 campaign.

If you want a fully polished, complete campaign today, you should probably wishlist the game and wait. If you like watching systems evolve and do not mind rough edges, Early Access is the right place to jump in.”

Approximately how long will this game be in Early Access?

“I currently estimate around 18 months of Early Access before calling the game version 1.0. That may change based on feedback and scope, but the goal is clear. Lock in a strong core, then ship a full story campaign on top of it.”

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

“The full version is planned to feel like a complete RTS built on top of the current foundation. Key goals for version 1.0 include:

• A full story campaign: A multi mission narrative from 1944 to 1957 that follows US OSS forces, a Nazi shadow group, Soviet rivals and key defectors. Expect amphibious landings, canal floods, Arctic convoys, Berlin quarantines and a final showdown over an Antarctic super reactor.

• More factions and tech trees: Expand beyond the initial USA versus Schatten conflict with new commanders and experimental tech styles such as prototype lasers, plague like mutators, gravity weapons and boarding focused forces.

• More handcrafted Operations: Scenario style missions inspired by campaign moments, such as convoy heists, desperate defenses, naval escorts and quarantine zones, that you can replay outside the campaign.

• Deeper systems: Expanded node specialisation, richer superweapon interactions such as flooding, infection, fog, tethering and boarding, plus more comeback tools so battles stay tense instead of turning into one sided snowballs.

• More maps and polish: A larger variety of biomes including Baltic coasts, Alps, Patagonia, Panama Canal, Atacama desert and Antarctic ice shelves, along with UI and UX refinement, performance tuning and smarter AI.”

What is the current state of the Early Access version?

“At the start of Early Access Terrors of War is in alpha and focused on single player content.

• Skirmish versus AI on multiple handcrafted maps, from tight factory brawls to sprawling countryside and coastal assaults.

• Scenario style Operations that echo planned campaign missions such as beach landings, lab raids, convoy protection and ambush, and base assaults, but without full cutscenes and branching story layers yet.

• The core economy and supply line system is already playable. You capture nodes, run convoys, protect depots and unlock devastating superweapons such as V2 strikes, nuclear attacks, clone swarms, bio weapons, mind control mines and heavy bombardments. These systems are being tuned during Early Access.”

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

“Yes. During Early Access the game will be cheaper to reflect its in progress state. As new systems, Operations and eventually the full campaign are added, the price will increase in steps. Early supporters keep their copy and all future updates.”

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

“I am relying heavily on player feedback to steer development. You can:

• Join the Discord through the link on this Steam page to vote in polls, share replays, report bugs and suggest changes.

• Post on the Steam forums with balance thoughts, scenario ideas and campaign feedback.

• Try new builds, then tell me what worked, what did not, and where the game should lean harder, whether that means gritty WW2, horror or wild experimental science fiction.

I read everything and regularly fold community suggestions into the roadmap.”

About This Game

Lead OSS task forces, fight over fragile supply lines and unleash forbidden superweapons in a brutal alternate history WW2 real time strategy game. Terrors of War mixes classic base building with experimental tech, bio horror and big, explosive battles that can mutate into outright nightmares if you push too far.

Early Access focuses on single player skirmishes and handcrafted Operations against AI. Over time those Operations grow into a full campaign that spans 1944 to 1957 and ends in a desperate assault on a super reactor buried in a frozen landscape.

Key Features

  • TLDR: Supply line focused WW2 RTS with weird superweapons, bio horror twists and fast, brutal battles against AI.
  • Supply line driven RTS economy that has no passive trickle income
  • Brutal, fast paced single player battles against AI
  • Devastating superweapons and bio horror experiments that can backfire
  • Replayable Operations mode inspired by planned campaign missions
  • A planned 1944 to 1957 story campaign with multiple perspectives and horror tinted set pieces

Build the War Machine: Supply Lines and Nodes

Terrors of War is built around a supply line economy instead of simple trickle income. If the trucks stop, the war stops.
  • Capture universal resource Nodes that boost income and increase your population cap.
  • Run vulnerable supply vehicles between fields, caches and depots. If your convoys die, your war machine stalls.
  • Specialise Nodes into Economy, Vision or Defense:
    • Economy makes more income and raises population cap
    • Vision reveals pockets of fog of war and warns about flanking forces
    • Defense creates tougher garrisons and stronger local defences
  • Fight over rail yards, farms, derricks, docks and secret labs. Each map has a fixed number of Nodes so you must expand, raid and cut enemy logistics instead of turtling forever.
Every truck you lose and every Node you let slip can flip the entire battle.

High Impact Combat and Superweapons

This is not a slow siege simulator. Battles hit hard and escalate quickly.
  • Command large combined arms forces of infantry, tanks, artillery and support vehicles in classic top down RTS fashion.
  • Use cover and garrisons to hold key chokepoints from factory catwalks to alpine bunkers and ruined city streets.
  • Unlock and deploy a terrifying experimental arsenal:
    • Nuclear and V2 rocket strikes that erase frontline positions
    • Clone swarm assaults and prototype super soldiers
    • Mind control mine drops that briefly turn enemy squads against their own
    • Bio weapon bombardments that drive units berserk
    • Gravity, laser and sonic prototypes that can cut through armour columns
  • Stack veterancy and upgrades to create elite spearhead units. Do not get complacent because a single well timed strike can erase your unkillable blob.
Every superweapon is a double edged sword. Used badly you will crater your own front line or contaminate the ground you meant to hold.

Operations Mode: Playable Now in Early Access

At launch Terrors of War focuses on replayable single player content that you can dive into immediately.

Skirmish against AI
  • Fight the USA against the Schatten shadow faction across handcrafted battlefields.
  • Tune difficulty, army sizes and AI aggression to your taste.

Scenario Style Operations
Tackle shorter, focused missions that are inspired by key moments from the planned campaign.
  • Amphibious assaults on fortified coastlines
  • Lab raids to steal prototype tech
  • Convoy ambushes and high risk escorts
  • Base assaults fought under constant superweapon threat
Use these scenarios to learn the economy, superweapons and unit synergies in controlled setups before you dive into larger wars.
Operations are the proving ground for the full campaign. Your feedback on balance and mission flow helps decide how future missions play, escalate and surprise you.

Planned Story Campaign: 1944 to 1957

The long term goal is a campaign that tracks the secret war behind WW2 and the early Cold War, told through multiple perspectives.
  • US OSS forces: Follow a covert task force from early raids on V2 facilities through farm country, industrial heartlands and frozen seas to the edge of the world.
  • Die Schatten: Step into the boots of the Nazi shadow program and use experimental reactors, clone vats and occult adjacent science to stave off collapse.
  • Cold War currents: See how Soviet rivals and key defectors twist the conflict with uneasy joint operations, quarantined cities and a three way showdown where trust or betrayal changes the final battle.
Expect a mix of mission types.
  • Classic base building conquests across rolling hills, fjords and nitrate fields
  • Outlier set pieces such as naval boarding puzzles on secret weapon convoys, frozen low resource maps with dangerous vents and canal flood defences
  • A pure commando style stealth raid behind enemy lines
  • Horror tinted operations with plague like mutators in ruined cities, infected districts that you must burn block by block, clone hordes spilling from vats and core nodes that pulse under frozen ice
Your choices, especially how you handle uneasy alliances and certain moral tests, will echo into late missions by adjusting voiceover, reinforcements, sabotage and final battle conditions.

All campaign content is planned and is being built during Early Access and is not fully available at launch. It is described here so you know where the project is headed.

A Solo Dev, But Not a Solo War

Terrors of War is created by a single developer but it is not meant to be a solo experience in spirit.
  • Discord and forums let you help set priorities whether you want more horror, more grounded WW2, more Operations or a faster march toward the full campaign.
  • Frequent balance updates and content experiments during Early Access. If a system is not fun it can change.
If you want a fully finished, polished campaign right now this is not there yet.
If you enjoy watching systems evolve, poking at strange RTS prototypes and helping shape a weirder, harsher strategy game, wishlist, playtest and tell me what to fix next.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some AI-generated content has been incorporated into the game. AI handles tasks like generating boilerplate code and other types of code assistance, freeing up time to concentrate on perfecting gameplay and making the user experience top-notch. Right now, a minor amount of audio and visuals you see are AI-generated, but as I move through Early Access, I'll be swapping some of them out for custom-made content from freelancers. It's all part of my commitment to delivering the best possible game and product for you, the gamer. In addition to the game, this Steam page has been reviewed and enhanced with the assistance of AI.

Mature Content Description

The developers describe the content like this:

Frequent depictions of intense war violence, including soldier casualties, vehicle explosions, and building destruction.
