Quality-of-life changes for gravships and shuttles, new snowy art, and mechanoid bosses in spaaaaaace!

Hello everyone, we’ve got a content update for RimWorld today!

Gravships have received some quality-of-life changes.

• The new gravship launch interface lets you get your colony’s animals and mechanoids onboard, and kicks visitors out. This makes takeoffs feel better and prevents accidental kidnappings.
• The pilot console now has a “view range” tool that shows your gravship’s range without going through the whole launch process

• Shuttles can now safely land on items, and they no longer obliterate a ton of roof when landing inside buildings – only the necessary roof.
• When you’re in orbit, colonists won’t automatically take off their life-saving, vacuum-resistant apparel if they’re in a dangerous vacuum.
• Mechanitors can summon the mechanoid bosses… in spaaaace!
• We added a new vacskin gland prosthetic from the Empire that protects your colonists against vacuum. (This cross-expansion content only appears for those with Odyssey and Royalty).
• We rebalanced the starjack xenotype to make them more useful in space – they have a new low gravity adapted gene which makes them faster and better workers while in orbit.

Other improvements include a new category for fishing in the work tab, tree sowing research allows you to grow timbershrooms in the glowforest, and the sentience catalyst now stops farm animals from roaming away.

And just in time for the colder seasons, there are new snowy visuals for trees and some plants!

We’ve also made several technical improvements to the game. We reduced the generation and loading times for worlds with 100% coverage, as well as added some tools to help our modders.

This update should be compatible with all savegames and mods. The full changelog is below to browse.

If you need to report a bug, or you’re having a problem while playing, please join us on the official RimWorld development Discord.

Have fun out there!
– Tia

Changelog

• Added snowy visuals for trees and some plants when they’re in a sufficiently snowy area.
• Added the vacskin gland prosthetic which protects against vacuum. Requires the Odyssey and Royalty expansion.

Improvements & Balance Changes

• Pursuing mechanoids in the gravship scenario now arrive in two massive raids per gravship map and then stop.

• Sentience catalyst now removes roaming and fence-blocked status from animals.
• The gravship scenario now requires you to start with at least one colonist capable of intellectual work. This prevents you from becoming immediately stranded.

• Archean trees now self-heal like other special trees.

Performance

• Reduce time required to load a 100% world save file.
• Reduce time to generate a 100% world by about 40%.

• Improve performance when hovering a world tile out of gravship range.

Technical & Modding

• Unify all MayRequire and IfModActive checks to strip suffixes, trim, and lower-case package IDs
