SotP 0.87 Warfleet Update

Greetings Fleetmasters and Admirals!

Today we're releasing version 0.87 of the Sins of the Prophets public alpha!

This update includes balance changes, bug fixes, and some art asset overhauls. A full changelog will be available at the bottom of the post, but I'll quickly go over some of the more eye-catching updates here.


Balance tweaks you'll notice include things like changes to cloaking as well as the Artemis and DOS gaining the ability to decloak*. Ships added to gravity wells via the Outlaw Sectors DLC are now faction specific. Titans have a fixed level for balance reasons. Ship abilities no longer cost antimatter in preparation for the upcoming strikecraft overhaul. Marathons now have an ability called "Falchion AP Missiles" that debuff enemy shield regeneration and armor*. The Valiant now has an ability called "Indra EMP Missile" the debuffs a single target's damage and weapon cooldowns. CRS and Charon classes can now reinforce friendly planets*. Hornet Mine health has been nerfed*. Sahara mine laying has had its cooldown nerfed. Rear-firing point defense has been added to most ships. The Flood are in the process of being retooled - one should use them at their own risk - be warned! For the full list of balance updates and too see more info about the "*" marked items above, see it at the bottom of the page!

Bug Squashing

Bug fixes are also detailed in the changelog, but include things like fixing instances where the AI could build two titans, or confusion with building titans caused by the previous attempts to balance their very powerful nature and the AI's visceral lust to build them as fast as possible. We've also make attempts to fix an issue where ships would travel outside gravity wells in normal space for vast distances causing issues for players and AI opponents alike. To attempt to fix this we've shortened the distances between planets, which seems to curtail this very odd behavior. We're also going to reach out to Ironclad to see if they know more about what causes this bug and give them our findings.

Art Updates

The art portion of this update is pretty juicy! It includes minor things like the addition of Banished, Swords of Sanghelios, and new UNSC player icons, as well as updates to weapon effects, ship ability particle effects, and updated point defense guns based on information shown in Halo Warfleet! Updated ship models include the CPV-class Heavy Destroyer, Halberd-class Destroyer, and the OSS-class Battlecarrier. You can see beautiful renders of those ships below thanks to Malcontent1692!

UI/UX Improvements

UI work continues - filling in absent ability icons, adding in more loading screens, creating unique launch and dock buttons for strikecraft (as seen below in gif form), info card tweaks, as well as event notification tweaks and fleet icons being given that SotP flair you all love so much (they're numbered too so you can keep track of each fleet as you play). Overall a lot of improvements that we hope you'll find enhances your immersion into our Halo experience.

Gettin' a whole lotta that "Ships want to manually traverse open space rather than jump from planet to planet" bug with the last update.

It almost always seems to be Covenant AI ships in their own Grav Wells on their own, but I've also seen huge fleets of Covenant ships chasing prowlers out into open space. I've had my UNSC ships try to do the same when just telling them to leave a Covenant controlled gravity well without using the retreat function.

UNSC AI also has a habit of hopping fleets between their own planets randomly and not actually attacking anything for hours at a time.

So, will we finally see buildable Stridents now that there's finally a canon source that says they're used outside the Infinity's complement as well? Warfleet pretty specifically mentions that the UNSC was building hundreds.

"In the aftermath of the war hundreds of multi-purpose Strident- and Anlace-class frigates were being assembled above mars and Tribute" They were launched alongside infinity and most likely unshielded by what we know now and refit later. Also if the AI could use them its all you would see and you'd get wrecked by Strident spam. Trust me I've seen it happen in the past.

I know it's kind of taboo around here to ask, but any idea when we'll see a post war version of the mod? Not asking for a date or anything like that, but are you guys targetting a release of some kind before 2018? Or some time later?

Buildable Stridents still won't be appearing until the post-war version of the mod, they would still mess with balance very heavily in the current version of the mod and we really don't see a place for them to fit. Rest assured though, post-war SotP will include buildable Stridents.

Im sorry but i still have the Bug that the AI is stuck outside the gravity well. Because of this they never attack me in full force. only some small ships here and there.

I play as the UNSC in the Will of the Gods map with 1 Covenant AI on the hardest difficulty as agressor.

Can you tell me some more details about the issue? What planet, how far in to the game, etc. Anything you can think of.

Reply Good karma Bad karma+2 votes

Also i made 2 screenshots of the glitch if that helps you.



Reply Good karma Bad karma+1 vote

well... the game tells me it's like 1 and a half hour into the game when i discovered the first covenant planet who has ships outside the gravity well. And it's almost every planet controlled by the covenant i discovered so far. Often they are outlaw ships or scouts. but there are also some warships.
The planets i discorvered so far who has it (not very much by this point) are:" Keldor, Y'Deio, and Ven III. It also happens often with my own scout ships and i think it has something to do when they are targetet by an enemy or are chased by one. Also my infinity once did it when i set her waypoint 2 jumps away and it tried to fly there with sublight while she was targetet by enemy ships. once i set the waypoint to the nearest planet she began to charge the jump. I don't know if this helps you but that's all i can think of right now.

I think Will of the Gods map for UNSC start is broken, I set it to the covenant for one of the team 2 but it always ends up spawning UNSC ships

Never mind, I realised you can't do 1 v 2
