Major Content Update - Willie's Rage
Hi everyone, We appreciate the feedback from our initial launch - we have taken your suggestions and criticisms and have applied them directly into a brand new major content update that is now live! PATCH NOTES WILLIE Rage - Throughout the contract, Willie has a chance of entering an enraged state, making him impervious to all damage. Players must quickly find a place to hide during this to avoid their demise Sneak - Willie has a newly added sneak capability, in which he will slowly attempt to creep up on players who aren't paying attention to their surroundings. This new behavior is intended to increase Willie's creepiness factor as his presence is less predictably noticeable In general, there is an increased involvement of Willie throughout the contract and a higher resistance to damage, making him more persistent in his pursuit of players {STEAM_CLAN_IMAGE}/44814956/cc805ba5f07a9f9a9a23eef978f7f67999b3fa39.png PLAYER MECHANICS Hiding - Throughout the Dry Dock Warehouse map, there are lockers than players can enter to become hidden, keeping you safe from AI. It's imperative to find a spot to hide during Willie's enraged state Players can now pick up both a wheel valve & fuse at the same time Players can now find a handheld map in the control room that can be brought with them and accessed throughout the contract All players are now visible on the compass when both alive and knocked down {STEAM_CLAN_IMAGE}/44814956/04381baa0cf9973b9a9d097f37fd513970180e4a.png EPISODE ONE MAP REWORK Each sector is now unique to help differentiate the different areas of the warehouse (cafeteria, offices, chemical storage, steamboat area, boat parts sector, etc.) The total number of rooms, paths, and doors has been reduced for an optimal flow and to reduce tedium in walking across a large map There is now one Keycard per sector which opens all respective utility rooms as well, further reducing tedium in finding keys Each door is now labeled and has a new module showing whether it's lo...Read full article on Community Announcements (NightmareForgeGames)Patch NotesOfficial
