After the Collapse

After the Collapse is a base-building and management game set in a post-apocalyptic world of urban and countryside environments. You lead a band of survivors, build a base, discover technologies and scavenge for resources while defending against raiders, mutants, monsters and environmental threats. You can manage populations from a few survivors to hundreds in real time, and dig through underground levels to explore caverns and sewers.

Build and defend a colony

You build colonies in procedurally generated environments with varied biomes, weather patterns, underground layers, resources and dangerous foes. Defend your survivors with automated turrets, traps and other defensive structures. As the world changes, plants grow, wither and die, weather affects crops, creatures roam the countryside and can enter your base, and rival factions compete for control of important resource production centers.

The game includes dozens of special events, including sickness, fires during heat waves, mental breakdowns, enemy raids and civilians asking for help. You can use captured enemies as workers or commodities, and tame giant creatures as pets, cattle or defenders.

Survivors and factions

In most scenarios and game modes outside Story Mode, you can choose from three survivor archetypes:

• Humans: technologically minded but weak in combat and likely to die easily in a fight. They can develop modern gear, weapons and automated turrets.
• Mutants: strong and immune to most sicknesses and weather effects, but prone to fighting among themselves and limited in their use of technology. They rely on exploration and scavenging to find and use more powerful weapons.
• Cannibals: willing to turn bandits and other hostiles into food, but unable to use their pre-war skills.

Expeditions and exploration

As the game progresses, you send expeditions across a dynamic world map to find survivors, scavenge loot and technologies, repair resource production centers, deal with other factions, uncover secrets and retrieve lost technologies. Factions compete for control of these centers, and you decide how to handle them. You can also explore forgotten bunkers through an interactive story system to uncover technologies, including the ability to build a customizable robotic army.

Story and game modes

The game offers a free-form base-building mode with light 4X elements, multiple scenarios with specific challenges, goals and quests, and an expansive Story Mode. Its long campaign follows a group of standard human survivors from their arrival at the bunker that sheltered them during the Collapse. Cutscenes and interactive quests establish the game's official lore, and the campaign's early stages also serve as an optional tutorial for newcomers. Story Mode uses standard humans; the other archetypes are available in other modes and most scenarios.

Modding

The game supports mods and the Steam Workshop. Its data, including items, creatures and events, is written in a text-based format, and advanced modders can use LUA.
