Current State of The Game Left Behind mode currently available and playable in single player with a multiplayer build currently in production  There are currently 4 enemy types implemented in their basic format of being able to see the player, chase, attack and a prototype search function if they lose line of sight. There are future plans to expand the enemies to give them unique properties and counters/weaknesses. Prototype crafting, building and survival systems are currently available to use however these systems are all subject to change as development continues Basic form of the health system detailed below is currently functional however there are several key changes to come. Sanity system detailed below is currently integrated in very basic form however there a several large scale changes and improvements to come. Multiplayer is currently disable due to issues with finding servers at this moment in time however the team is hard at work in rectifying this matchmaking issue in order to reintroduce this to the project and allow players to play the currently available modes together. Planned features and content There will be four main game modes included within the project at full release with staggered releases of content throughout the early access period. The four modes are story mode/campaign, left behind/stranded mode, requisition mode and tactical operations mode. Story Mode - Story mode will feature a full campaign split into several acts that can be played solo or with up to 6 players in co-op with plans to scale difficulty based on player count and tweaks to be made to puzzles through to factor in more players and deepen immersion. Left Behind/Stranded Mode - This is the survival mode in which you play as an operative left to fend for yourself in the other dimension, with no extraction available and only your wits you must scavenge and craft whilst maintaining your base as you explore and search for a way home. This is a closed experience that may add some context or lore to the story/world with its own story. This mode will feature enhanced survival features compared to the other modes such as base building and more player stats such as hunger, thirst and temperature  Requisition Mode - This mode tasks players with exploring a large procedurally generated map looking for the precious crystals and their power, the players will be given a quota to reach and once they have fulfilled the quota they may leave. There are plans to add player progression that allow players to customise the loadout they take into this mode. Any surplus crystals will give players bonuses and extra cash to then spend on upgrading their gear and or character. The map for this mode is generated from a series of pre made grid squares, these level chunks define what kind of zone spawns and then handle the generation and placement of all objects, entities and puzzles when the map is loaded to ensure variance throughout the map if multiple zones of the same type spawn. Tactical Operations Mode - This mode will feature a catalogue of different missions and modes that will score the player based how they perform and if all objectives are completed. These missions will run in parallel to the story mode offering further insight into certain events with the campaign whilst also offering some completely separate experiences and stories for the player to explore Play alone or as a team Players are given the option of completing the game in single player or teaming up with other players from around the world to tackle the challenges within.   Procedurally generated map In Depth Health System Health is divided into several states each with corresponding debuffs that are applied dynamically and emphasise the importance of managing resources and staying healthy  Sanity System Staying physically healthy is not the only worry when traversing the game world, the sanity system works similarly to the health system but the lower your sanity becomes the more at risk you become, featuring auditory/visual hallucinations and more
