Ebbtide FOB: Announced Base Structures and Supply Rules
Explore the Ebbtide FOB structures and supply rules announced by ProjectAlive, including walls, weapon positions, ammo depots, fuel points, and base defense.
An Ebbtide FOB is a forward operating base that you choose where to build. ProjectAlive describes walls, weapon positions, ammunition facilities, and fuel points as parts of the base-building system. These installations connect combat units to the supplies they consume during the campaign.
An Ebbtide FOB is not a separate mission outside the campaign map. The operations map and battlefield remain connected, and your forces can only rearm and refuel at bases you hold. This Ebbtide FOB guide covers the announced structures and supply rules, rather than an optimal layout or a tested build order.
Ebbtide FOB Structures and Fortifications
The official description lets you choose where to dig in and build a forward operating base. It names HESCO and concrete walls, gates, and scaffolding used to defend the walls. Building materials have to be delivered to the site; the walls are not described as independent of the supply system.
| Building Group | Options Named by ProjectAlive |
|---|---|
| Perimeter | HESCO walls and concrete walls |
| Wall fittings | Gates and scaffolding to defend the walls |
| Weapon positions | Gun nests, CIWS, and mortar pits |
| Facilities | An ammo depot, a fuel point, and lighting |
These are the building options listed on Steam. The listing does not give construction costs, a preferred placement pattern, or a complete building sequence. Treating the list as a ranked set of upgrades would add information that ProjectAlive has not supplied on that page.
Supplying an Ebbtide FOB
Soldiers, vehicles, and aircraft consume ammunition and fuel. The announced rule is that they can only rearm and refuel at bases you hold. Construction has its own transport requirement: building materials for walls arrive by hooklift truck or helicopter sling.
| Supply Detail | Announced Rule |
|---|---|
| Ammunition and fuel | Consumed by soldiers, vehicles, and aircraft |
| Rearming and refueling | Available at bases you hold |
| Wall materials | Hauled by hooklift truck or helicopter sling |
| Transport network | The horde hunts convoys and cuts roads |
The Steam description connects these systems by asking you to keep supply lines open. It does not give convoy escort requirements, a resupply timer, or numerical depot capacities. An Ebbtide FOB reference can explain the relationship without inventing those values.
Base Defense and the Wider Campaign
The Nexus is the hive mind controlling the horde. Its announced behavior includes ambushing convoys, cutting roads, besieging bases, and hunting stranded units. ProjectAlive also describes attacks that matter to defensive positions and nearby troops.
| Horde Behavior | Official Description |
|---|---|
| Barriers and rooftops | Zombies pile up to climb walls and rooftops |
| Low-hovering helicopters | Zombies can cling to helicopters close to the ground |
| Fallen soldiers | Soldiers killed by the horde rise again as zombies |
| Supply routes | Convoys can be ambushed and roads cut |
Fire support can be called from the operations map or battlefield. The listed options include M777 howitzers, HIMARS rockets, destroyer guns, and carrier aircraft. Ship magazines are finite, and heavy weapons can bring buildings down. These are announced campaign mechanics, not evidence for a particular Ebbtide FOB placement strategy. See the official Ebbtide Steam page for ProjectAlive's description.
FAQ
What can I build at an Ebbtide FOB?
The announced Ebbtide FOB options include HESCO and concrete walls, gates, scaffolding, gun nests, CIWS, mortar pits, an ammo depot, a fuel point, and lighting.
How does an Ebbtide FOB resupply units?
ProjectAlive says soldiers, vehicles, and aircraft can only rearm and refuel at bases you hold. Ammo depots and fuel points are listed among the base facilities; numerical capacities and resupply timings are not given.
How do wall materials reach an Ebbtide FOB?
Wall materials are hauled in by hooklift truck or helicopter sling. The horde can attack convoys and cut roads, which connects Ebbtide FOB construction to the campaign's supply routes.
