Ebbtide has no named heroes, commanders or soldier archetypes - no characters, no bosses, no bestiary of named infected. What it has instead is a roster of real hardware and real-world ground forces. ProjectAlive has demonstrated most of these individually through development devlogs between September and October 2026, which makes the roster unusually concrete for an unreleased game.
Ground forces
National Guard - the US ground forces you begin the Los Angeles theatre with.
LAPD - Los Angeles Police Department units, also available at the opening.
Marines - deployable ground forces brought in as the campaign escalates.
Armour
M1 Abrams - the main battle tank, and the unit shown under direct control in the devlogs.
T-90 - the opposing-pattern main battle tank, available as a unit in the roster.
Bradley IFV - infantry fighting vehicle for supporting the ground line.
LAV - light armoured vehicle, fast and cheap for the early push.
Humvee - light utility vehicle for rapid redeployment.
Fire support
M777 howitzer with MRSI - long-range artillery support for the heavy end of the spectrum.
TOW anti-tank guided missiles - dedicated anti-armour capability.
Napalm air support - air-delivered incendiary against massed hordes.
Airstrikes, destroyer naval gunfire and Tomahawk cruise missiles - the heaviest support options in the escalation path.
Aviation
Attack helicopters - with rappelling demonstrated in devlogs, dropping troops directly onto a position.
Transport helicopters - moving the force, and running the supply routes that must be defended.
Base defences
High walls - the first layer of a fortified position.
Frontline bases - forward emplacements that let you fight outside the wall line.
CIWS (close-in weapon systems) - anti-missile and anti-swarm coverage over the defended area.
What is not documented
No in-game economy, tech tree, research tree, XP system or upgrade tree has been documented for Ebbtide. No named infected variants, special enemies, elites or bosses are verifiable either - the horde is described generically. Exact unit build costs and wall durability numbers have not been published. Treat any site claiming otherwise with caution.
