The Left Behind Horde Mode and Endless Wave Guide

Horde concentrates combat into a wave loop. It can be played alone or in player-hosted online or LAN co-op, with up to four players in supported multiplayer sessions. The official mode information identifies endless wave-based play, but it does not provide a complete enemy schedule or numeric wave table.

A combat-first mode

The objective is to survive repeated attacks rather than uncover Story's mystery. Melee and ranged weapons are confirmed parts of the broader game, while food, water, and health form its limited resource categories. Players should plan around what they find instead of expecting a full crafting or base-building system.

Solo and team options

Solo play places all awareness and resource decisions on one player. Co-op lets a group divide sightlines and communicate about supplies. No dedicated-server support is confirmed; sessions are player-hosted.

Horde includes three named maps: Vila, School, and Pool. These spellings come from the official mode information and should not be expanded into invented layouts or environmental features.

Vila

Vila is one of the three selectable arenas. Its exact dimensions, spawn locations, and defensive positions are not specified in the confirmed facts, so map-specific claims should wait for official documentation or the release build.

School

School is the second confirmed Horde map. The name identifies the setting, but it does not by itself establish room access, chokepoints, item placement, or enemy entry behavior.

Pool

Pool completes the listed set. As with Vila and School, official information confirms its inclusion without publishing a full layout or loot table.

Endless Wave is identified as new at full release. It remains a wave-loop combat experience, but its defining conditions are constant nighttime and paths that become available within maps as play continues.

Always-night combat

Unlike the broader daytime-looting and nighttime-defense rhythm, Endless Wave keeps combat at night. That condition removes the expectation of a normal daylight phase and makes visibility and sustained readiness central concerns.

Unlocking paths within maps

Official wording confirms that paths become available within the maps. This refers to access opening during play, not a published list of permanent unlocks. Costs, triggers, timing, persistence between sessions, and the exact path sequence have not been formally detailed.

Different from standard Horde

Standard Horde and Endless Wave share repeated combat, but Endless Wave's always-night condition and changing map access are the named additions. It should also remain distinct from Survival, which uses the open world, has no story, and frames repetition around a new high score each game.

Sound preparation can be described without inventing enemy types or values. The safest guidance follows confirmed mechanics: manage food, water, and health; use melee and ranged weapons; communicate in co-op; and take advantage of available environmental access.

Establish team responsibilities

In co-op, assign players to watch separate approaches while preserving the ability to support one another. Call out health needs and weapon finds rather than silently collecting everything. Because detailed scaling by player count is not confirmed, avoid assuming that adding players changes waves in a particular numerical way.

Treat new access as a decision point

When an additional path becomes available in Endless Wave, reassess sightlines and exposure before moving. An opening can provide space but may also change where players must watch. Exact consequences vary by map and are not officially documented.

Preserve limited resources

Food, water, and health are the resource categories. Boarding windows and storing items are confirmed light interactions, but there is no full construction system. Use ranged weapons and melee options according to immediate need without relying on an unconfirmed crafting plan.
