Hey Everyone!

Update 21 is here and has a strong focus on the much-requested mods in co-op and introduces custom asset importing as well as many other improvements!


🔶 Gameplay

Systems:

Balance Tweaks:

New Eliminator starter:

LS30 Blackout


The LS30 Blackout gives Eliminator a bit more of a marksman type of specialization which was always intended but didn't really come across so well. The second kit already provided a perfect benefit for a precision playstyle but the framing didn't really work. Blackout now rewards careful play with powerful stat benefits and is a more rapid-fire variant of the Sniper version.

New Uncommon Machine Gun:

L8 Squad-LMG


The new L8 provides a sturdy and reliable mid-game option for Heavy gunner and other classes alike. It might not have the best accuracy but it's large capacity and consistent output allows it to kitted in a flexible way and potentially scale well.

New Legendary Launcher:

ANH-8 Annihilator


The classic Annihilator returns with powerful laser explosions and a new alternative ammunition type. Use at your own risk!


🔶 Mods in Co-Op are live!

You've asked for it many times and it's finally here!

U21 had a big focus on modding and we worked hard on making mods work properly in online co-op gameplay! When opening up a lobby, you can now select as host which mods to share with the lobby and joining players can conveniently and correctly download the latest version they need.

Tons of new community content is right at your fingertips!

(Remember you can press control on a character to inspect the actions, in case you suspect a mod spamming or see performance issues with a certain mod. Naturally we can not provide support for any custom mod content or performance issues coming from a mod)


🔶 Editor Overhaul

Varied elements of the editor have been improved and we made a general pass on the UI elements and menus. This is not 100% perfect visually yet, but under the hood a lot of clean-up has happened. The Editor was a quite old and complex UI but now got a lot more maintainable and much easier to use for everyone!

New: Audio Pitch Preview

New: Stat Preview

New: Unified Navigation

New: Depot overview

We will also follow up with some updated video tutorials soon.


🔶 Asset Importing

Asset importing is finally here!

You can now import:

Check the Import Custom Assets button in the Depot Settings.

Note: While 3D Model importing is technically possible, for characters this requires more setup from us and is not as trivial. Weapon models can already be imported with the correct slots. A example GLTF can be found here:

🔶 UX

We did a bunch of improvements all around UI and UX:


🔶 Co-Op / Networking

Improved reliability for important network messages

We’ve added an extra game-level reliability system for important messages, instead of relying only on Steam P2P’s built-in reliable messaging.

This should help fix cases where players could sometimes get stuck between levels, enemies or objects did not appear correctly, or other important game events failed to show up.

Late last year, we switched to Steam P2P for peer-to-peer support after many players requested it. Since then, feedback has shown that Steam P2P’s reliable messaging has not always been reliable enough for our needs, so we’ve built our own additional reliability layer on top of it.

Update 20 already added this system for entity spawning, which addressed reports of enemies not appearing. This update extends the same approach to all “must-receive” messages.

Other

We’ve also made intermediate disconnect messages in chat less noisy when the connection quickly recovers.


🔶 Fixes

As usual, we worked on a lot of fixes:

We also welcome back a former Employee, Michal, which is has the role of a full time QA (Quality Assurance) Specialist, helping us from now on with finding and solving issues and improving overall Game quality : )
