Tally4: Operation MARY

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.
