Faction Playstyle Guide

This page is not a traditional S-tier balance chart. Sanctuary: Shattered Sun is pre-release — the July 2026 demo and upcoming Early Access will rewrite unit stats, economy tuning, and matchmaking before any fair “best faction” claim exists. Instead, use this guide to match EDA, the Guard, and the Chosen to how you actually want to play.

How to read these recommendations

We rank fit, not power:

• Primary pick — the faction that most naturally supports the playstyle.
• Secondary pick — viable with different execution.
• Stretch pick — possible but fights your instincts or needs extra skill.

When the game patches, revisit this page — and read individual faction guides for deeper doctrine.

Aggressive / early pressure

Faction	Fit	Summary
EDA	Primary	Human mass, artillery timing, and extractor denial sync with rush plans.
Guard	Secondary	Swarm floods work once production spins up; weaker in the first minutes.
Chosen	Stretch	Elite armies need Flux banks; reckless rushes waste expensive units.

Aggressive players should master Attack Move and never ignore economy — even rush builds fail without Flux. See the full EDA guide for combined-arms pushes.

Macro / economic scaling

Faction	Fit	Summary
EDA	Primary	Efficient throughput and population scaling reward wide expansion.
Guard	Primary	Swarm into experiments — economy feeds both quantity and tech swings.
Chosen	Secondary	Strong late if you survive; tighter margins while banking Flux.

Macro lovers should internalize the Flux economy guide before judging factions. Guard and EDA punish idle extractors differently: EDA converts lead into unstoppable mass; Guard converts lead into vision plus prototype timing.

Beginner-friendly

Faction	Fit	Summary
EDA	Primary	Clear goals, forgiving losses, straightforward unit roles.
Guard	Secondary	Good if you like scouting; multitasking required.
Chosen	Stretch	Small armies punish mistakes — better after RTS basics.

New players: start with how to play the demo, then how to choose a faction, or use the faction picker tool.

Recon and map control

Faction	Fit	Summary
Guard	Primary	Superior recon tools and expendable harassment.
Chosen	Secondary	Smaller footprint, precise picks on key targets.
EDA	Secondary	Wins vision through forward presence if you build for it.

Information wins Dyson Sphere campaigns where relays and elevation matter. Guard players who never scout still lose — tools do not replace habit.

Defensive / late-game pivot

Faction	Fit	Summary
Chosen	Primary	Shields and energy weapons scale into elite defense.
EDA	Secondary	Artillery walls and population re-builds stabilize lines.
Guard	Secondary	Experiments swing stalemates if economy survives harassment.

Team games and flex picks

In team modes, complementary pairs often beat triple-stack mirrors:

• EDA + Guard — mass front with recon/backline harassment.
• EDA + Chosen — meat shield plus focus-fire delete.
• Guard + Chosen — vision and precision picking off key targets.

Communication covers vision gaps Chosen players feel solo.

Quick decision flowchart

1. Want to attack within ten minutes? Lean EDA.
2. Want to see the whole map before fighting? Lean Guard.
3. Want every battle decided by micro? Lean Chosen.
4. Still unsure? Run the faction picker and play two demo skirmishes per faction.

Pre-release disclaimer

No faction here is permanently “S-tier.” Demo feedback, Chris Taylor’s design iterations, and Flux tuning will shift matchups. Treat this guide as a playstyle compass, not esports gospel. Deep dives: EDA · Guard · Chosen.
