M28AI Devlog (v177)
-
Granted i don't know how to play air player, but even if i did i don't know if i can make enough ASF's to counter 3 enemies each having ASF's. Previous games i hit 1000/1000 unit limit with 500 ASF's and whenever we engaged in neutral territory, it wasn't even close, i guess you did some good programming since they seem to combine shots to 1 shot my ASF's like flies.
On this map there are some things i need to do. First 1 mega to each entrance and 3 SMD's to cover the whole base. Otherwise my allies will die either to nuke or early experimental. Now if i add ASF's to this, my eco just cant do it.
Yes, they were building ASF's but absolute numbers its a huge difference. They donated 6 ASFs to me and i never saw any of them having more than 10 ASF's. If you look at enemies, they each prolly have 100's of ASF's. Was just wondering what triggered this, it was pretty frustrating.

You could try fighting against M28Easy (with normal M28 as teammates), as the 2 M28 will be at less of an advantage when fighting for map control against 3 AI. Alternatively use AiX for the enemy team and set it to a below 1.0 modifier.
If you send spy planes to scout enemy nukes then your M28 teammtes should also build SMD over their own base.
-
Tnx. I played another of that type of game but with flying experimentals disabled. Was fun.
This map is wierd. Right from the beginning, even though i go totaly turtle, my team mates always manage to push land 3/4 of the way to the enemy base. Spamming 99% land units. Enemy on the other hand goes hard air right from the start and eventualy kills the advancing units and takes 3/4 of the base. It would appear that when enemy is outside our walls, it will build more land units, presumably it sees them as greater threat. But after an hour or so when we cleared our doorstep and reclaimed killed enemy units (which was my plan from the start), suddenly both allies went heavy air. In the first hour enemy vs our air was 1 to 30 for enemy. All of the sudden it became 50/50 and then we won air. I didnt play air from the start, to see if that will trick allies to go heavy air. Didnt help.
Im wondering. Do AI's respond to chat ? Are there any commands they will recognise? Like, e pls, build smd, etc. ?
-
@goblinsly2 No, it doesn’t respond to chat or pings
-
@maudlin27 Just wanted to report that whatever crashes were happening with nukes are gone, played a 4 hour match with no slowdowns and problems.
I wanted to ask you about ASFs, just to make sure my eyes aren't deceiving me. AI is using some strategy, like preventing overkilling in ASF vs ASF battles ? In battles when it seems we both have equal amount of ASFs and i do attack move, my ASF's drop like flies and he seems to keep most of the planes.
It's great for practicing air combat for total air beginner like myself. But just wanted to see if im using attack move wrong, or AI is making air calculations that just arent possible for me. Like AI checks health of a single ASF and then only uses amount of its own ASFs targeting this plane enough to kill it. How do pros do it against this AI in air battles?
-
@goblinsly2 Attack move is generally a bad option for air fights. Stop micro is probably the best option unless you are a pro; pros will often instead manually move the asf group to try and get then to ‘turn’ to be behind the enemy asf group.
To test, use sandbox and cheats to compare how 100 asfs on attack-move do against 100 asfs on stop micro. I expect the faf training discord could provide more help in this if you need.
AI uses a different approach for simplicity (and to avoid cpu issues) but this approach doesn’t take account of overkill (at least directly) for asf fights IIRC; it’s also likely either fighting over SAMs or has superior numbers if it’s engaging your air force
-
@maudlin27 Hello, I wanted to ask whether there is possibility of disabling AIs microing on campaign maps, I know it's possible to do that for skirmish. Thanks in advance!
-
@fumoenjoyer Not currently an option but I've noted it down to add in a future update.

v84 Update
23 changes and fixes. The majority of changes were based on lower priority points from an AI vs AI test replay I ran for v82 relating to early game plateau expansion/defence.- Added new M28Easy option for hostile campaign AI
- Plateaus/islands with some hostile enemies should still be considered for drops where there are a number of available zones (e.g. resolving an issue on Adaptive Tourmaline where civilian PD prevented a drop on the main map area)
- Inties should be more likely to defend plateau drops from enemy air attack, while the plateau drops should no longer be diverted to reclaim duty if they have yet to build a land factory
- Improved the ability of engineers to dodge T1 Cybran and UEF bombers by pre-emptively dodging - where previously they would almost always die to the first volley now they have a decent chance of surviving at least 1 bomb.
- Reduced the tendency of M28 to build T1 arti early on instead of tanks
- Increased ACU aggressiveness in the late T2/early T3 stage in teamgames.

v85 Update
20 more tweaks and fixes, based both on some more minor issues noted from earlier replays, and some improvements to deal with a live replay I saw where M28 threw away a game-winning position on dual gap (by not attacking t2 arti with destroyers, and pausing its SMD when the enemy built a nuke). Changes include:- Land units should sometimes try and suicide into enemy mexes instead of retreating
- Naval units such as destroyers should be much more likely to attack enemy T2 arti and other fortifications if not badly damaged (once they have control of the pond) instead of hanging back to support longer ranged units
- Fixed a bug that caused SMD to be paused before being loaded when the enemy has a nuke
- Ythotha should consider focusing down enemy T3 land units to try and reduce the likelihood it change its orders so much that it doesnt fire it's big 'lightning ball' (these changes may also cause it to cancel this attack, but hopefully it will reduce the worst case scenario of it not even killing the t3 land unit before cancelling the lightning ball attack)
- Slightly improved Novax targeting so if it's relatively near a shield that a friendly T3 arti has just brought down the novax should move to kill the shield (previously this would only happen if the shield was almost in range)

v86 Update
Hotfix for mostly minor bugs. 14 tweaks and fixes, with the more impactful ones being:- Added a fix to take account for FAF changing the categories of the paragon a couple of weeks ago (which meant M28's paragon specific logic was disabled)
- Engineers should be far less likely to try and reclaim low value wrecks such as trees in their build range (and instead either not reclaim, or look further afield for high value wrecks)
- Greater prioritisation of air (at the cost of most experimental production) if the enemy has an air experimental and M28 lacks air control
Acknowledgements
- x17 - Replay where M28 failed to respond properly to being gifted a paragon

I see a few updates were done since i wrote about air. I thought i improved my airplay and started winning because of that, but it might just be because of updates.
I just finished a great game where i sniped a paragon and only when my bugs attacked it i saw 2 coms standing next to it. That looked very dangerous. Just a thought.
I think the only reason i am able to win in this setup is because i build fabs while enemy doesn't, so after a while i just build more units. I remember M27 mass built fabs and ras coms, this seemed to change in M28 ?
-
v87 Update
39 fixes and changes, including:- Fixing a bug with nomads air units (which would constantly be sent for refuelling due to an issue with nomads which shows them as having negative fuel)
- Fixing a bug with reading a map that caused M28 to break on Adaptive Zone 6
- Pre-emptive gunship retreat logic based on how many SAM missiles are approaching them
- Fixing an issue on some maps where if M28 was on team 2 it would treat some frontline bases as being 'safe' eco/air slots
- Fixed a bug preventing battleships from groundfiring subs if the enemy had any non-sub units nearby
- Teammates are more likely to build lower tech power if stalling energy even if a teammate has a factory of a higher tech
- Various adjustments to the decision on what experimental to build
- Various adjustments to ACU upgrades, making it more likely defensive upgrades are obtained (instead of RAS), and that the ACU will consider cancelling an upgrade even if in its core base
Acknowledgements
- Radde - Various replays in a range of scenarios providing the source of many of this verison's updates
- Relent0r - Identifying a bug with nomads that causes air units to be treated as having negative fuel
Trophies
- Radde trophy - Awarded to Radde and KuhwaKlimakleber (for beating 1.4 resource on a 15km mapgen)
(No change to the Sladow trophy, held by Radde beating v81, 1.5 AiX on a 10km map)
-
v88 Update
17 fixes and changes, including:- Ahwassa targeting improvements so they are more cautious against enemy SAMs when M28 only has 1
- Fixed some edge cases with experimentals where they could be in range of an enemy experimental and not attack it
- Mobile shields should adjust to try and shield the closest friendly combat unit on the frontlines.
- Significant increase in frigate proportion vs other naval units
- T1 aeon factories should build far fewer T1 arti once T2 land is reached
- Multiple naval HQs should be much less likely to be obtained
- Fixed an issue where engineers could try and reclaim high value wrecks and sit idle due to no such wrecks existing
Acknowledgements
- Azraeel – 1.1 resource replay (prompting me to make ACU’s MAA escort more likely to retreat from enemy tanks)
- No change to previous trophy award

The AI seems great but I'm not sure if I'm setting them up wrong or what.
Using all default settings in a 2v2 scenario, the enemy AI will spam T2 MMLs, but once this force is overwhelmed they're pretty easy to beat. Seems like a great AI early-game for smaller battles, but larger 4v4 battles the AI seems very confused and doesn't really know what to do.
Definitely the best AI available though, so cheers for that!
-
As mentioned before, I do agree that this is by far the best AI there is for FAF.
Let me just try to follow up the other message that I sent above on M28AI playing the Seraphim. Because in the many games that I've meanwhile played, it seems that the Seraphim come with a bit of a challenge of their own for the AI, making it a much less challenging opponent. Energy management appears to be an issue, possibly in conjunction with the Quantum Rift Archways. After it has built a QRA (and it always builds multiple), it struggles with energy for quite some time and is keeping shields down etc. Also, it's typical for the AI to run into unit cap issues later, also complaining about it in the chat, while it keeps piling up all units in its base.
https://replay.faforever.com/22323052 is an example for this. It is having energy issues before, but after completing its 4th Quantum Rift Archway at 1:25, it takes until 2:09 (almost 45 minutes) to get it's energy handling back up and the shields stable.
Also, what the AI never tries as a Seraphim is building (their unique) nuke launchers for nuke spamming, or mass attacks with air units. Also experimental unit attacks as such are very rare, but that might just be because of the energy problems caused by the Quantum Rift Archways.
This is not intended as a complaint, but just as hopefully helpful feedback to improve this AI even further!
-
@koral If it’s spamming mmls that suggests you’ve built a firebase near enough that it sees it as a threat.
For 4v4s if you’re easily beating it with a team of lower rating than the AI send me the replay and I can see if there are any obvious issues, as it should be compatible with virtually all maps and settings
-
@hammi Is the QRA the modded experimental unit that builds t3 land units quickly? I can probably reduce the chance it gets built slightly depending on how the unit’s blueprint is defined
I’d expect the Yolona Oss to be built in high eco games, but it’s also possible that the mods used interfere with the normal logic for building this.
-
Yes, the QRA stems from the Blackops FAF: Unleashed or the Total Mayhem mod. Not sure if the issue is (only) how often it is built. Energy management gets out of control, and the units are essentially just kept in the base. The first issue renders all shields useless, and the second causes all this investment to be essentially invain. But I guess it's not easy/possible to fix energy management?
