This guide will be focusing on the changes from the hard mode / awakened mode, however of course it hasn’t got everything like the new monsters.
The basic changes
-Gamemode only playable after beating the game once (you then have to buy the lantern in the shop, you can use it in the lobby to make the game hard mode if you are the host, then you have to buy it again)
-PermaDeath, no revival
-No midgame joining, however this seems to be broken
-Pets (equipable in player apperance)
The important changes
Perma death ain’t a joke – once you are dead you remain a spectator.
Several new enemies, the most important one being the Shambler / Ghost.
Enemies / Entities
The Shambler, Threat: Medium
A ghost that will randomly appear on the submarine. It will target one player and attack them. An attacked player will be teleported into an alternate world and will have to try to escape.
He has a tendency of getting stuck and usually disappears after 7 secounds, however don’t let his “harmless” behaviour fool you – being in an alternate dimension at the wrong time can be a death sentence.
Note: I have only been teleported to one so far.
An alternate dimension will usually include several strong enemies including the ones the time traveller can spawn, be underwater / no air, and several confusing background elements.
Players in the dimension should run to the right side as fast as they can as the exit is usally there. Don’t take risks and try to fight; not only are the enemies strong, the lack of air puts you on a time trial, and permadeath is no joke. Just run to the right side until you’re out!
Drone, Threat: Medium
This creature seems simmilar if not replaces the swordfish in the normal depths. It can be very annoying so make sure to dispose of it early.
Worm, Threat: Low?
A green worm-ish creature that can spawn inside the dark depths. It will try to come near your submarine and grab it, however it dosen’t always hit. Concequences of a grab are unknown to me.
Tiki Orb Spawner, Threat: None?
Green Tiki-ish heads that spawn in the volcanic depths. They follow the submarine at slow speed and spawn green orbs, however colliding with the heads has no effect, neither does destroying them. You can either kill them just in case or leave them be for possibly less enemy creature spawns.
Green Orb, Threat: Helpfull?
Green orbs that spawn from the spawners. They have no known gameplay effect. It is suspected that travelling trough biomes does not make them dissappear, which would explain why they re-appear in later biomes without any spawners. Their emitted light could be considered helpfull.
Any other entities not listed:, Threat: Yes
There may be more entinites not listed, so be aware.
Best Submarine: Crevette
Players: 3-4, experienced, in voicechat, all have time
Gear: 1 normal wrench, 2 normal/pipe wrenches, 1 optimal item (recommended: Medkit)
Avoid attacking civs unless you have got gun, then you could maybe pick a fight with most.
Go for a balanaced power build, always have a shield.
Save batteries / EMPs / fuel for diffilcult battles.
