"Supply is what keeps the fight going." Units can only rearm and refuel at bases you hold, and every wall needs materials hauled in. Official
FOB structures
"Choose where to dig in and build a forward operating base." Official
| Structure | Purpose |
|---|---|
| HESCO walls | Perimeter barrier |
| Concrete walls | Perimeter barrier |
| Gates | Let your units in and out |
| Scaffolding | Lets soldiers defend from the walls |
| Gun nests | Fixed defensive fire |
| CIWS | Close-in weapon system |
| Mortar pits | Indirect fire from the base |
| Ammo depot | Where units rearm |
| Fuel point | Where vehicles and aircraft refuel |
| Lighting | Visibility around the base |
Structure list from the store page. Official Purposes are as the store implies ("add gates and scaffolding to defend the walls"); costs and build times are not published.
Supply: ammo, fuel and materials
- Everything consumes. "Soldiers, vehicles and aircraft burn through ammunition and fuel." Official
- Only your bases resupply. Units "can only rearm and refuel at bases you hold." Official In the ops-map video a tank out of ammunition must be resupplied before its main gun fires again. Dev
- Walls cost materials. "Every wall needs building materials hauled in by hooklift truck or helicopter sling." Official
- Convoys are targets. "The horde hunts your convoys and cuts your roads, so keep the supply lines open." Official
Three official videos focus on this loop: "Build a FOB. Then Hold the Line.", "Your FOB won't resupply itself." and "The FOB is built. Now it needs supplies." Dev
Convoys on the operations map
- Send truck and helicopter convoys carrying supplies, troops or refugees. Official
- The Nexus ambushes convoys and cuts roads; you get a warning before an attack and can reroute, retreat or call in fire support. Official
- Helicopter slings skip blocked roads but bring aircraft close to a horde that climbs onto low-hovering helicopters. Official
Upgrades, automation, economy: not announced
People search for upgrade paths and automation in base builders. For Ebbtide, none of that has been described: no tech tree, no building upgrades, no automated production, and no resource numbers. Supply moves when you send it. We will add these sections if the playtest shows them.
FAQ
Is there base building in Ebbtide?
Yes. You choose where to dig in and build a forward operating base with HESCO and concrete walls, gates, scaffolding, gun nests, CIWS, mortar pits, an ammo depot, a fuel point and lighting.
How does supply work in Ebbtide?
Soldiers, vehicles and aircraft use up ammunition and fuel and can only rearm and refuel at bases you hold. Every wall needs building materials brought in by hooklift truck or helicopter sling, and the horde hunts your convoys and cuts your roads.
Can you upgrade bases in Ebbtide?
No upgrade or tech-tree system has been described. What is confirmed is the list of structures you can place and the supply that keeps them working.
Does Ebbtide have automation?
Not as a feature that has been announced. Supply moves by convoys you send yourself, by truck or helicopter. No automated production or supply chains have been described.
