Castles, Keeps, and Forts (Legacy) For new version go to Castles Keeps and Forts Remastered. This version still works


This is the original "Legacy" Version of Castles Keeps and Forts,
The entire mod has now been remade and remastered from the ground up for a much better experience

Future CKF content will now be focused on the new CKF Remastered version Linked below and future CKFR mods.
CKF (Legacy) still works in game perfectly. No further content will be added to this mod.

I would highly recommend migrating your servers and games to the new CKF Remastered version of this mod at start of your next server season or play through, as the remaster has more feutures a better and enhanced snap system and many more features and quality of life improvements. To go to the the new CKF Remastered steam page click the large image link below;

Love the mod!!!! One request though... can you make the "Keep Sloped Half Wall" into a "Peek" so that it will create a nice finishing touch with the "Keep Roof Ridge"....
N7_Shadow Apr 24 @ 1:21pm 
Zgames1234 No, they are not exactly the same size. You can use some pieces from vanilla in a limited way, but for starters, the foundations are slightly different in size, and I do mean slightly.

I realy like the mods of Castle and keepr, in the begining we where able to choose ice building, can you please bring that back so we can use is on the ice maps and snow Bios

does this use vanilla sizes for builds
N7_Shadow Sep 18, 2022 @ 8:16pm 
I think he made the new version use the same size blocks as vanilla, because people wanted to be able to use vanilla blocks with this mod. The problem isn't the mod maker. The problem is game devs don't seem to understand that 8 foot walls may look fine in real life, but in game, the ceiling looks unnaturally low, so people use double walls. This could be fixed if they just gave us 12' x 12' blocks instead of 8' x 8' blocks. This would allow single blocks to be used for a wall, instead of 2 blocks. This would save on CPU resources also. Less blocks to make a base, ship, etc., in these survival games that use blocks to build with.

I just found this and it kinda make the "remastered" look like you just cut it in half and called it better.

Does anyone know if this Mod is at all compatible with his newer version of CKF?

TC25 Jul 16, 2022 @ 11:17am 
I wish someone could make or take this mod and make it like the CKFR version to contain all the engrams in the work bench, to cut down on engram bloats.
