What is WTT?

What is Welcome To Tarkov?

Welcome To Tarkov (WTT) is a mod for SPT AKI that has been in development for over a year. What started as a small passion project has grown in size to incorporate 15+ core members as well as contributions from other well-known mod authors and friends of WTT alike.

How does Welcome To Tarkov change the game?

As a mod, WTT overhauls SPT AKI, touching on almost every vanilla game system, as well as adding completely new systems to the game and its core mechanics. Inspired by open-world hardcore survival projects like STALKER: Anomaly and STALKER: GAMMA, WTT takes SPT’s artificial multiplayer MMO difficulty adders and replaces them with a challenging world economy, loot scarcity rebalancing, a lore friendly quest overhaul, and a map-traveling system built from rewritten portions of the Traveler mod allowing seamless travel between maps. Aside from its changes to the game’s core properties, WTT also adds to the world’s variety of traders, NPC’s, characters, items, and quests:

  • Over 1,000 custom bundles adding new weapons, attachments, wearables, containers, food, medical, and barter items.
  • New bosses with their own custom gear that will be properly incorporated into WTT’s quest lines.
  • New, meaningful traders with their own lore-friendly quests and narrative elements to help the player progress through the story-line of WTT.
  • New playable characters and outfits that will add to the player’s customization abilities.
  • New quest types incorporating brand new map extraction points, putting the player’s knowledge and familiarization of SPT’s maps to the test.

Welcome To Tarkov stands as one of the largest mods created for SPT AKI thus far.

When does Welcome To Tarkov release?

Thursday.

Fixed more gameworld.mainplayer references for fika headless compatibility Added packet delivery system for static spawns for fika compatibility

This version works for fika and spt, it only loads the fika helper assembly if fika is present. This should hopefully fix the last issues for headless crashing on raid start, but if there are still issues let me know!

Sorry, I should mention that my mod is utilizing the CustomQuestService, CustomItemServiceExtended, and CustomQuestZoneService assemblies. I know some of the functionalities are working, however I haven’t had a chance to test the CustomQuestZoneService portion yet. I’m very new to dev work so my confidence is iffy.

Should be featured, lets be honest.

this is a client utility mod that doesn’t really have much use for regular users save for being a dependency for them to install other mods. primarily it’s for modders, and featured is usually for set-complete mods that are creative or original. this may be both, but I don’t think this fits the requirements
