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;

I've just released a new mod called Snap Fixer Plus that is mostly aimed at CKF mod users.
Main bullet points:
- Adds S+ Snap Compatibility to CKF parts (CKF Legacy, CKF Remastered, and CKF Science Fiction). Currently supports S+ and SuperStructures. Crop Plots, dedi storage, etc
- Scales CKF Legacy parts to correct size, to fit with other structure mods properly. This is optional and must be enabled via ini. The main reason is because building with rescaled CKF Legacy parts means if you ever remove my mod, the parts will have visible gaps between them (since they're normally slightly smaller).
- Fixes some snap issues with CKFR and CKF:SF. These fixes will eventually make there way into the actual mods, but for now, installing this mod will fix them. Main ones are better triangle foundation snapping, and better fence support snaps, and fence supports can be placed even if AllowIntegratedSPlusStructures=false

Would be cool if he removed all the weapons and stuff, and put it in a separate mod, so you can have just that, with the new mod.

Is there any issues if I pair this mod with the new remastered one? I like the weapons and seigecraft stuff in the old one.

Has anyone found spawn codes that work for the arrows/bolts ? the posted ones seem to not work at all

@FluffyBunnykins Did you ever get an answer on whether or not you can run this mod with the remastered version? If not, I'm going to give it the old college try.

Spiral staircases are a staple of castle architecture (They were implemented to keep attackers from having even the slightest advantage by keeping their sword hand as close to the center column as possible).

I'm not as into the rounded foundations, walls, etc. as everyone else seems to be but it would definitely look great with the spiral staircase.

@Nerevar I run it and S+ on our cluster and have had zero issues
