ARMORED COMBAT EXTENDED
The definitive engineering and combat framework for Garry's Mod.
What is ACE?
ACE is a comprehensive engineering framework for Garry's Mod that replaces legacy building tools with realistic physics simulation and authentic components. From engines and drivetrains to advanced sensors and weaponry, ACE challenges you to solve real engineering problems. Whether you're new to advanced building or a veteran seeking depth, ACE rewards skill and creativity with systems that actually behave like their real-world counterparts. Actively developed since 2018 with a passionate community and consistent updates.
Core Systems
Advanced engineering components and realistic physics for serious builders
Realistic Mobility
Authentic engines, gearboxes, and drivetrains. Build vehicles that handle like the real thing without thrusters or legacy workarounds.
Advanced Physics
Penetration mechanics, spalling, composite armor, ballistics, scalable components, heat, damage system — you name it. Your designs faces real engineering challenges.
Modular Components
Extensive library of parts: propulsion systems, weapons, sensors, electronics, and specialized equipment. Mix and match to solve problems your way.
Immersive Feedback
Dynamic lighting, advanced sound propagation (including speed of sound simulation), and visual effects that make your creations come alive.
Wiremod Integration
Seamlessly integrates with Wiremod for turrets, movement, targeting systems, and whatever else you can imagine.
Open Source & Community-Driven
Fully open source with active development, community extensions, and direct developer engagement. Potentially, with future payouts.

Our Story
Evolution of the Source Engine combat standard
The Spark 2015-2018
ACE began as a passionate vision by RDC to modernize combat building in Garry's Mod. What started as balance tweaks evolved into a complete overhaul, introducing advanced composite armor, realistic ballistics, and modern components. On September 4, 2018, the project went fully open-source, inviting the community to help shape the future of the mod.
Foundation & Stability 2019-2023
As the playerbase grew, so did the team. Developers like Mr.Marty and Cheezus joined forces with KemGus to professionalize development. This era focused on code quality, bug crushing, and stability. The result was a robust framework that could handle complex machines without crashing, leading to a successful Steam Workshop launch and a thriving ecosystem of user-made content.
The New Standard 2024-Present
Today, ACE continues with its mission to become the gold standard for engineering in GMod. We are committed to keeping ACE free, open-source, and community-driven forever.
