Species: Unknown's zombies, Poulpi and killer robots crawl into every Company moon, loaded from your own copy of the game.
How to join the host presses Host in Lethal Company's main menu and opens the lobby (Public or Friends only), then friends join it from Lethal Company's lobby list or through the host's Steam invite. Up to 4 players, each with Lethal Species and Species: Unknown.
Ten creatures, the gear, the supply stations, the loot, the HSS Hawking and a moon for it, all from Species: Unknown, come to Lethal Company. Their real models, textures, animations and sounds are read from your own installed copy of Species: Unknown when you start the game.
The main menu becomes a chase: a Company employee with a B19 Pistol and a Motion Scanner runs across the Hawking-7 crater at night with Species: Unknown's specimens on his heels and the crashed HSS Hawking's alarm lights behind them. The title is Lethal Company's LETHAL over Species: Unknown's SPECIES, and Species: Unknown's main theme plays (both can be turned off in the config).
A moon of its own, not a copy of a Company moon: the impact crater where the HSS Hawking came down. Route there from the terminal (hawking, $550). You land beside the real Hawking from Species: Unknown, hundreds of metres of hull lying half buried in the crater floor. Walk up to its docking-bay airlock to go aboard; the ship's siren is still sounding. The fire exit is a breach further along the hull, lit by burning wreckage. The Hawking's shuttle lies wrecked near the landing site, and the crater floor is shaped differently on every landing. The specimens are much more common here than anywhere else, and the scrap is worth about 25% more. Its risk level, scrap and specimen numbers can be changed in the config.
Species: Unknown's research vessel, rebuilt from its own decks: the central hub, the crew quarters and the laboratory, with corridors, stairs and rooms where Species: Unknown put them. Its sliding doors open as you walk up and close behind you, and the ship's own lights stay on. Its Ammo Stations stand where the ship keeps its ammo boxes and its Medical Points where its health stations are. It is the interior on Hawking-7 and turns up now and then on the Company's moons.
Aboard the Hawking it is quiet apart from Species: Unknown's hangar hum, until the containment breach. It comes at a random moment, anywhere from about 40 seconds to 5 minutes after landing, and sometimes comes back later in the day. An alarm blares, the lights stutter red and 3 to 6 crew zombies get up off the floor somewhere near you. It always happens aboard the Hawking, and there is a small chance of one in any other facility.
Sold in the Company store and delivered by drop ship:
Prices, rounds per ammo box and Hawking-7's route price can be changed in BepInEx/config/melty.lethalspecies.cfg.
Species: Unknown's own stations stand inside the facility, usually one of each per moon:
Each use left shows as a light, an empty station shows a red lamp, and the prompt counts down to the next refill. In multiplayer the stock is shared: everyone sees the same counts, and each player waits a few seconds between uses. Uses, refill times and waits can be changed in the config.
18 kinds of scrap with Species: Unknown's own models spawn in every facility alongside the Company's, about a third of what you find: credit chips, stacks and caches, hard drives, keycards, the Black Box, bio canisters, microscopes, centrifuges, toolboxes, oxygen tanks, surgical saws, bone cutters, desk lamps, potted plants and sample cases. Carry them home and sell them like any other scrap.
The explosive canisters are worth the risk: drop one off a ledge, hit it or shoot it and it goes off. The Fire Canister explodes like a landmine; the Frost Canister freezes every creature around it for 6 seconds. Set one down near a specimen and shoot it.
The creatures spawn on every moon through Lethal Company's normal spawning, show up on your scanner, and can be hit or stunned like any other enemy. Built and balanced for solo play; up to 4 players can play together, and every player's game builds the same moon and ship.
