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?

“Tally4: Operation MARY is a new kind of flight game — a military aviation thriller with physics-based flying, large-scale combat, and a narrative campaign playable from both sides of a conflict. Building something this ambitious as an independent studio means we need real pilots in the cockpit giving us feedback. Early Access lets us put the flight model, multiplayer, and core combat in players' hands while we continue developing the full campaign and expanding the game.”

Approximately how long will this game be in Early Access?

“Approximately 6 months. The core systems — flight dynamics, multiplayer, and Instant Action — are already functional. Early Access will focus on completing the campaign, polishing based on player feedback, and expanding content.”

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

“Early Access includes Instant Action with procedurally generated single-player, PvP, and co-op scenarios, the core flight model for the FA-18 and SU-33, and After Action Review playback. We plan to add the full dual-sided campaign — playable from both the US Navy and MARY Alliance perspectives — along with additional aircraft, expanded multiplayer features, and co-op campaign support. We also plan to refine the flight model, AI behavior, and overall game polish based on community feedback throughout the Early Access period.”

What is the current state of the Early Access version?

“The current Early Access build includes fully functional physics-based flight dynamics for the FA-18 and SU-33, online multiplayer with PvP and co-op modes, procedurally generated Instant Action scenarios, and full After Action Review with session playback. The game is playable and stable, but content is still being developed. The campaign is not yet available in Early Access.”

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

“We plan to increase the price when the game leaves Early Access. Players who support us during development will get the game at a lower price and help shape its direction.”

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

“Community feedback is central to our development process. We will actively engage with players through our Discord server and Steam discussions, track bug reports and feature requests, and use multiplayer data to balance the flight model and combat systems. Every session is recorded and reviewable through After Action Review, which helps both players and us understand what's working and what isn't. Players who fly early shape how the game evolves. Every session is recorded through After Action Review. If something goes wrong, players can share their AAR replay directly with us — we see exactly what happened, making bug fixing faster and more accurate. Players who fly early shape how the game evolves.”

About This Game

Opening paragraph (the hook)

Hawaii, 1996. A rogue military alliance has seized the islands, deploying MOLOT — orbital kinetic strike weapons — and KUPOL, an advanced air defense umbrella that turns the sky into a kill zone. The United States Navy scrambles to respond, but conventional tactics won't work against unconventional weapons. Welcome to Operation MARY.

What is Tally4: Operation MARY?

Tally4: Operation MARY is a military aviation thriller — the kind of game Tom Clancy would have made if he built flight games instead of writing novels. This is not an arcade shooter with a flight skin. This is not a cold systems simulator where you flip switches for fun. This is something new: a combat flight game with physics-based flying, a grounded military thriller narrative, and battles involving over 200 aircraft in the sky at once.

You don't just fly missions. You live through a crisis.

Two Sides. One War.

Play the full campaign from both sides of the conflict:

US NAVY — Scramble FA-18 Hornets from carrier groups to challenge a fortified enemy that controls the sky above Hawaii. Break through KUPOL's layered defenses, strike MOLOT platforms, and turn the tide against a force that was never supposed to exist.

MARY ALLIANCE — Fly SU-33 Flankers under the protection of KUPOL. Enforce the occupation. Execute missions that test your loyalty — until the moment everything changes. When the alliance turns on you, your only option is to run. If you survive the escape, you switch sides and bring what you know to the fight against the system that once protected you. If you don't survive — that's where your story ends.

Physics, Not Gimmicks

The flight model is built on real aerodynamics. Your aircraft responds to physics — not scripted animations, not simplified arcade rails. Feel the difference between an FA-18 and an SU-33 in how they handle at the edge of their envelopes. Weight, thrust, drag, and lift matter here.

Scale That Matters

This isn't you versus three enemy fighters. Operations in Tally4 involve over 200 AI aircraft — strike packages, interceptors, escort flights, and defensive patrols all operating simultaneously. You are one pilot in a war, not a one-man army.

Never an Empty Server

Most multiplayer games die when the player count drops. Tally4 doesn't have that problem. Our AI pilots are trained on real player flight data — every dogfight, every evasion, every tactical decision made by real people feeds into AI that flies like a human, not a script. You will never join an empty server. You will never wait in a queue. Whether there are 100 humans online or just you and a friend, the sky is always full and the fight is always real.

Built to Beat

Tally4 is built around one loop: fight, lose, learn, win. Instant Action generates combat scenarios that challenge you. Fly them solo. Fly them with friends in co-op. Get shot down. Review what happened in After Action Review — rewind, switch perspectives, study every move. Try a different approach. Try again. And again. Until you crack it.

Then share your replay and show the world how you did it.

This is the arcade machine philosophy — hard but fair, punishing but beatable. The AI doesn't cheat. It just flies like a real pilot. And when you finally outmaneuver it, you earned it.

The AI Gets Better. So Do You.

Every flight you take — single player or multiplayer — trains the AI. The community's best maneuvers become the AI's tactics. The more people play, the smarter and more unpredictable the opponents become. Today's AI is dangerous. Tomorrow's will be worse.

Single player isn't a lesser mode. It's where you prove yourself against the collective skill of every pilot who ever flew in Tally4.

After Action Review

Every sortie is recorded. Once the fight is over, review the entire engagement in full AAR playback — rewind, fast-forward, switch perspectives, and study the battlefield from any angle. Understand what happened, why it happened, and how to fly it better next time.

Instant Action

When you want pure combat without the story, Instant Action generates scenarios on the fly:

  • Solo — Test yourself against AI trained on real player data

  • Co-op — Team up with friends to take on AI-generated threats together

  • PvP — FA-18 vs SU-33, online multiplayer dogfights

  • Procedural scenarios — No two sessions are the same

Built for Flight

Tally4 supports keyboard and mouse, Xbox controllers, and HOTAS flight sticks. This game was designed to be played with a stick in your hand.
