About This Game

CosmoLaunchSystem is a hybrid game about running a space agency: combining budget and contract management with rocket building and physics-based 2D flight.

You are the agency director. You accept contracts, invest in research laboratories, design launch vehicles in the VAB, and deliver client payloads—ranging from early suborbital flights to LEO, GEO, and narrative-driven space telescope missions, as well as CubeSat systems that allow you to launch various scientific instruments into orbit for your clients.

Who You Are

Space agency director. You don’t just fly—you decide what to build, when to launch, and how much to risk your reputation and budget. Bad weather, untested designs, and mid-flight failures can destroy a client's payload. Good decisions unlock lucrative contracts and milestone steps in exploration.

Build Like an Engineer

In the modular VAB editor, you assemble rockets from parts: liquid engines, SRB boosters, fairings, RCS thrusters, fins, command pods, and payloads. See real-time mass, thrust, TWR, Delta-V, and Center of Mass.

Save proven designs, upgrade your hangar, and roll out vehicles to the pad. Tuck delicate payloads inside aerodynamic fairings, and mount scientific instruments directly onto the rocket body.

Fly and Reach Orbit

Control throttle and pitch in a realistic atmosphere—complete with drag, Max Q, and the risk of structural failure from pilot error.

For stable orbit missions, a pitch guidance radar helps with recommended ascent profiles to reach the target orbit, but the final outcome is up to you. A more precise orbit yields better bonuses and agency reputation.

Physics: altitude-dependent gravity, exponential atmospheric density, Time Warp, SRB vibrations, plasma effects at Max Q, and exhaust plume lighting.

Run the Agency

Time flows on a turn-based system: budget, science points from the lab, rocket construction, and an inbox featuring contracts, weather reports, and mission briefings.

• Budget and Reputation: Success unlocks better jobs; disasters hurt financially and public relations-wise.

• Tech Tree: Invest in the laboratory to unlock new parts and capabilities.

• Testing and Reliability: Trajectory simulation and mass-dummy test flights before launching actual contracts.

• FDIR: Mid-flight anomalies, a diagnostic console, and an optional FTS (Flight Termination System).

Key Features

Who Is This For?

For fans of space agency management and rocket building who love orbital physics. If you like "brick-by-brick building" but also want a strong layer of business, contracts, and base progression—this is the game for you.

AI Generated Content Disclosure

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

In the development of this game, artificial intelligence was used in the following areas:

Code and Logic: Game algorithms (including the autopilot systems and the mission generator) were developed with the assistance of AI-powered programming tools and assistants.

Graphics and Audio: Selected graphic/visual elements and the audio design were generated using artificial intelligence tools.

The game does not use generative artificial intelligence to create content in real time during actual gameplay—all assets were pre-generated and are part of the static game content.
