The framework underneath every LHDF mod: JSON settings per mod, saved data in the vanilla save, one Game Master attribute tab, admin rights, a shared world index and a work queue.

• Your character comes back after a restart: gear, position and health.
• All LHDF data (accounts, vehicles, bases) is kept in the server save.
• Game Masters get one "LHDF" tab to change the server live.
• Long jobs are spread over many frames, so the server keeps its frame rate.

Traders, player accounts and cash. Buy and sell items, vehicles and helicopters in a shop window, bank your cash, and let the server check every trade.

• Your account balance is safe on death; carried cash ($100, $500, $1000 notes) can be lost and looted.
• Bank at the traders: deposit cash, withdraw it, or send money to another online player.
• 8 shop types: General store, Gun store, Outfitter, Medic, Vehicle and Helicopter dealer, Bank, and a hidden Black market.
• Shop window with categories, search, 3D previews and item stats, for mouse and controller.
• Vehicles are delivered next to the trader and can be sold back, priced by their health.

Enemy AI encounters and missions: zones, camps, patrols, location enemies, encounters near players, missions with tasks and rewards, and directors that adapt sectors.

• Zones, camps, patrols, ambushes and squads wake when a player comes within 600 m.
• Cleared encounters come back after a while, never right next to players.
• 17 mission types, from clearing and sabotage to rescue, hunts and last stands, in the normal task list.
• Mission rewards: items at the target, and money split between the players who were there.
• Directors run sectors of the map and decide what moves into ground players have cleared.

Loot in buildings and on open ground, spawned near players and removed when nobody is near. Five loot modes, a vanilla item pool and Game Master areas.

• Every building has a loot type (residential, medical, police, military, commercial, industrial).
• Loot appears when you come close and is removed when nobody has been near for a while.
• The same roll comes back on your next visit until the respawn time is over.
• Named places (cities, towns, bases, airports, ports) raise or lower the loot chances.
• Magazines come with a random fill.

Food, water, energy and body temperature: eat, drink from canteens, wells and rivers, stay fed for energy, stay warm, or take damage.

• Food and water fall faster when you run, swim or carry a heavy load; energy comes back when you are well fed and rest.
• Night, rain, wind and height make you cold; clothing, shelter, vehicles and fires keep you warm. Wet clothes warm less.
• Drink from canteens, wells, pumps, taps and rivers (not the sea).
• Low values cost you health regeneration and stamina; at the end you take damage.
• A small HUD shows a value only when it gets low. Values survive logout and restart.

Vehicle ownership, locks and keys: lock and unlock, give keys, hand over, claim, a manage window and a vehicle spawner. Owned vehicles are saved.

• Lock your vehicle: nobody without access gets in, opens the storage, refuels or repairs it.
• Give keys to friends, take them back, or hand the vehicle over, in one manage window.
• Owned vehicles are saved with position, damage, fuel and cargo, and the garbage system leaves them alone.
• Vehicle spawners keep a vehicle at its spot and replace it once it is taken or destroyed.

Map Entity Hider, Safe Zones with damage, weapon and AI rules, and search, sort and filter in the Game Master entity list.

• Safe zones: no player or vehicle damage, no weapons or explosives, and AI that stays inside is removed.
• Map Entity Hider: clears buildings, trees, rocks or walls from an area, and the AI navmesh follows.
• Game Master entity list with search, sorting, a faction filter and group members.
• Everything placed is kept in the server save.

Join banner and loading screen, scheduled chat messages, #message, #save and #info, view and world rules, Game Master access and corpse times.

• The server rules on join, and again with "Server info" in the pause menu or #info in the chat.
• Scheduled server messages in the chat.
• The loading screen stays until the area around you is loaded.
• The second weapon slot takes rifles and other long guns.
• A random starter loadout for new players and after death.

Bigger vanilla backpacks: twice the capacity and twice the weight, and rifles, machine guns and most launchers fit into the larger packs.

• Every vanilla backpack carries twice as much, by volume and by weight.
• Packs that held 6000 or more now take rifles, machine guns, sniper rifles and most launchers.
• Medical bags and RPG packs keep their item size limit.

Optional pack for Lost Hope Survival: BetterInventory, WCS Weather and voice ranges with earplugs in one mod.

• BetterInventory: a cleaner inventory with a larger vicinity preview.
• WCS Weather: fog, rain and thunderstorms with lightning.
• Voice range (whisper 3 m, talk 10 m, shout 60 m) on F2, and earplugs in six steps on F4.
