Solo Indie delivers a local 1-4 player split-screen physics-based create and combat sandbox with scientific tools for PvP or PvE. Replay many unique campaigns. Master your hex build strategy, microscopes, and chemistry skills. Be clever to achieve victory and learn as you go. June NEXT FEST.

1-4 Player Multi-player modes supported: PvP Local, Co-op Local.<h2 class="bb_tag" >Architectural Integrity. Deterministic Combat.</h2> DODECIUM is a science-based 3D action-strategy shooter engineered by a Principal Systems Architect for the competitive purist. In an era of &quot;feel-good&quot; aim assist and non-deterministic jitter, DODECIUM delivers a high-fidelity simulation where victory is a product of superior logic and mechanical precision.<h2 class="bb_tag" >The Deterministic Core</h2> Built on a custom-hardened Godot 4.6 framework, DODECIUM utilizes a fixed-point math library to ensure absolute state synchronization. Whether you are playing solo or in 1-4 player local split-screen, every molecular collision and projectile trajectory is calculated with zero-drift accuracy. No ghost hits. No netcode excuses.<h2 class="bb_tag" >High-Stakes Microscopy Integration</h2> Combat is driven by a deep scientific tools layer. <ul class="bb_ul"><li> Strategic Depth: Adapt your loadout based on complex cycles. </li><li> Physics-Based Combat: Use 3D spatial awareness to solve high-intensity tactical puzzles. </li><li> No Hand-Holding: Experience a game with no aim-assist, designed for those who demand a high-skill floor.</li></ul><h2 class="bb_tag" >Local-First, Privacy-Focused Engineering</h2> We prioritize the player's sovereignty. DODECIUM features a lean, professional deployment with: <ul class="bb_ul"><li> Zero 3rd-Party DRM: No intrusive background processes. </li><li> Native Linux/SteamOS Support: Optimized for 1280x800 on Steam Deck and 4K on high-end Supermicro/Alienware rigs. </li><li> 7.1 Surround Audio: Positional data streams for maximum spatial tactical advantage.</li></ul> Building the future of competitive strategy. One logic-gate at a time. Add DODECIUM to your Wishlist to support the upcoming Steam Next Fest Technical Preview!<h2 class="bb_tag" >⚛️ 💻 ⚙️ 📐 STEM / NGSS Aligned with Automated Formative Assessment</h2><h2 class="bb_tag" >Parents &amp; Educators: True STEM Learning</h2> A High-Fidelity Physics Sandbox Unlike arcade puzzle games, mechanics are driven by a strict, real-world physics engine. The gameplay naturally aligns with Next Generation Science Standards (NGSS) for Middle and High School Physical Science (MS-PS3, HS-PS3 / Grades 6-12), allowing players to directly manipulate mass, velocity, and thermal dynamics to solve complex stealth scenarios. Automated Formative Assessment Unlike traditional educational sandboxes that require parents or teachers to build extensive external lesson plans, this game does the homework for you. Featuring integrated, auto-verified CER (Claim, Evidence, Reasoning) assessments, students cannot progress without demonstrating conceptual mastery. Turn Screen Time into Lab Time As players solve levels, they compile their simulation data and export beautifully formatted PNG &quot;Lab Reports&quot; directly to their desktop—guaranteeing high-fidelity data with zero extra grading. Ready to print or upload seamlessly to Google Classroom, Canvas, Schoology, or any major LMS. Educator Fact Sheet: <ul class="bb_ul"><li> Pedagogy: Supports Inquiry-Based Learning and Problem-Based Learning (PBL). </li><li> Assessment: Built-in formative assessment via CER generation with auto-verified progression. </li><li> Core Concepts: Physical Science, Systems Thinking, Energy Transfer, and Cause-and-Effect Modeling. </li><li> Accessibility: Supports diverse learners with remappable controls and accessible UI design. </li><li> Safety &amp; Privacy: Fully COPPA &amp; FERPA Compliant. No in-app purchases, no user data tracking, and no external internet requirements for gameplay.</li></ul> --
