+# Multiplayer — Maps & Game Modes
+
+## Maps
+
+- **10 maps total** at launch
+- Design philosophy: **CSGO-tight** — intentional lanes, clear sightlines, no wasted space
+- Subspace Continuum's Trench Wars maps were too large and too open — avoid this
+- All maps are 2D top-down space environments (asteroid fields, space stations, nebulae, etc.)
+
+| Map Size | Used For |
+|----------|----------|
+| Small | Ranked 5v5 |
+| Medium | Ranked 5v5 / Casual 25v25 |
+| Large | Casual 25v25 only |
+
+---
+
+## Ranked Mode — 5v5
+
+Competitive, skill-based, MMR/ELO ladder. Penalty for leaving mid-match. Small–medium maps only.
+
+### Ranked Mode Ideas
+
+| Mode | Description |
+|------|-------------|
+| **Flagship Assault** | Each team has a Flagship (large ship). Destroy the enemy Flagship while defending yours. *(Recommended starting mode)* |
+| **Control Point** | One central point on the map. Hold it longer than the enemy to win. First to X seconds wins. |
+| **Deathmatch** | First team to X kills wins. Clean, simple, easy to understand. |
+| **Relay Capture** | A neutral carrier drifts across the map. Escort it to the enemy base to score. |
+
+> **Suggestion:** Start with **Flagship Assault** only. It's unique, has natural tension (offense and defense), and maps can be designed around it. Add modes later as seasons.
+
+---
+
+## Casual Mode — 25v25
+
+No penalty for leaving. Larger maps. Chaotic and fun — you can drop in mid-match.
+
+### Casual Mode Ideas
+
+| Mode | Description |
+|------|-------------|
+| **Sector Control** | Map divided into sectors. Hold more sectors at time limit. Ties to galactic war meta. |
+| **King of the Hill** | One contested zone in the center. Hold it to rack up points. |
+| **Annihilation** | Pure kills. Last team standing or first to X kills. Chaos mode. |
+| **Base Assault** | One team attacks a fortified base, one defends. Roles swap each round. |
+| **Convoy Escort** | One team escorts a slow-moving freighter across the map, other team destroys it. |
+
+> **Suggestion:** Start with **Sector Control** for casual. It ties into the galaxy meta (Helldivers-style), encourages teamwork without hard requirements, and naturally scales to 25v25.
+
+---
+
+## Galaxy Meta (Helldivers-Style)
+
+- The galaxy is divided into **sectors**
+- Casual 25v25 matches determine which race controls which sector
+- Ranked 5v5 results also contribute to sector control
+- A live galaxy map on the main screen shows the current war state
+- This gives low-stakes players (casual) real impact on the ongoing war
