ok, is it just me or is the advent beam turret upgrade 'synergy' rotten compared to the other factions' turrets? i mean vasari gets to shut down regeneration for ages and tec can get both an aoe missile ability and a long range attack that reduces enemy armor??

It's definitely not as good, but on the other hand Advent turrets benefit a lot from the shield bestowal of their hanger.  Usually people use synergy turrets as an alternative to weapons upgrades for their starbase, freeing up slots for other purposes.

While the TEC longer range attack is certainly very nice, the sheer amount of damage that clusters of Advent turrets put out is pretty insane.  Human players will know to steer clear of these, but against the AI, I think this is in fact the most powerful of the turret upgrades.  It is definitely the weakest upgrade when it comes to trying to provide a little protection to a large area, but clusters of turrets backed by hangars with shield bestowal and/or a starbase create a "zone of death" bar none.

The real disadvantage of Advent beam platforms is that you need several of them to receive much of a benefit (hence "synergy")...even one or two TEC/Vasari point defenses are useful since meson bolt/disrupter nanites make for good focus firing...Advent beam platforms however don't provide the same FFing capabilities unless there are tons of them...

how do you kill a tec starbase with 20000+ hull, fully upgraded weapons, strikecraft upgrade(s), and hangars being protected by it? bombers dont work because i had to switch all my strikecraft slots to fighters just to hold off his own strikecraft, and they were barely able to scratch the ridiculous hull and shields. moving the fleet close would risk being hit by the red button attack (the ai must have been at that tier already). it took me a long time to realize that it wouldnt have the self destruct because weapons+hull+sc would already fill all the upgrade slots, but i still didnt have enough of a fleet to directly attack it.

The answer is still bombers. Flak to protect your own fleet and use your bombers to nuke the hangars then the SB. What faction are you playing? If Advent then TK push to defend your caps and shield bubble  over the battle ball.  If Vasari then abuse scramble bombers. You can also sacrifice a subverter or two to reduce shield mitigation then use an Egg for a final kill with the armor reducing ability (risky). For flak one option is to send them along the path the bombers take from the Argonev.You can also have your flak follow your HCs around while they kill the rest of the orbital structures. If you are worried about some units meandering towards the SB then use hold position. Your own fighters should torch the bombers also. How many strikecraft are you attacking with?

Haha what about 2 Orky's with 20,000+ health, 8,000+ shields with all weapons upgrades in the same grav well. The Sins Plus mod makes this disaster possible lol. Lucky I am TEC in extreme late game so I have hundreds of thousands of credits due to a 15+ jump trade route as well as many many frigate factories to replace the losses (coupled with industrial juggernaut tech and the artifact that improves fleet construction by 30%)

Still its an insane battle, each grav well is a major victory lol 

If you're the TEC, you can also take some Ogrovs and pound it from afar. If you're really paranoid, you can take an Akkan with Targeting Uplink to give them more range, and if you happen to have Tier 7 military techs available, you could research Extended Range Missiles for an extra 4%/8%/12% range. With that much range boost, even Javelis LRMs can join in and add their fire.

Fighters are actually not all that good against fighters...flak is far far better, and capital ship abilities (flak burst, magnetize, TK pusch, Jam weapons) are very handy...I have a distorted intuition on this since I play with a mod, but fighters in general don't suppress bombers very well, especially when there are lots and lots of bombers...

If you are TEC, ogrovs + bombers are a good way to deal with starbases...wiping out support structures first (repair bays, hangars) should be your first priority...having an akkan with targetting uplink is also very useful...garda's should be fine for dealing with enemy fighters...

If you are Advent or Vasari, then lots and lots of bombers...

If this is an AI starbase, then honestly a full fleet could probably just shred the TEC starbase...once your bombers have been whittled down by enemy fighters, just throw in tons of LRMs and/or Kodiaks....if it is a human starbase, be careful as it likely has the red button on it....

Seleuceia brings up a key point. Is this vs AI or a human player? If AI then people (including myself) have offered multiple solutions and you don't need to fear the red button. If human then either a) bring enough bombers or ogrovs (if TEC) or go around and avoid the starbase completely. You can always strip the rest of the grav well like locusts and then move on.

The strikecraft from the Argonev should not bother you much while you pillage his orbital structures if you have enough flak and properly position them. Most human players put the SB right at the edge of the phase lane to trap you after a jump, so beware the red button. But if you scout well enough you can usually (I stress usually) go around.

Personally I fear an Orkulus backed by hangars with phasic trap much more than an Argonev. ANd if it is also supported by a  fleet with supporting overseers and subverters then it is time to pull out a Kostura else gg. Transcencias can also massively suck with the huge range of mass disorientation and meteor control. If I ever see a human player with a Transcencia fully loaded with strikecraft I will get up and do a little happy dance since it means he completely messed up his upgrade choices.

i was playing advent,

thanks for all the help people

i encountered essentially the same situation in a different game. i'm sure that with enough bombers and no opposition i could eventually whittle through the base, but i only had 19 (and 10 fighters, because flak would get killed by the sb if they tried to chase their fighters), and they brought their fleet in before i could even take down its shields. the problem is that i couldn't get another fleet supply upgrade because my 5-planet economy was already low, and the ai had a larger empire than me. it had made allies with one of the other ais in the system, while the fourth one was hostile to everybody. i also couldn't move on to the next planet because all my ships would lose half their hp and all of their antimatter.

Yeah, that isn't going to kill a heavily upgraded starbase very quickly.  It will kill it given enough time, but you'll need some patience, and if the starbase has a sizeable chunk of flak defending it you're out of luck.

You have a couple approaches, but trying to beat the starbase and the enemy fleet simultaneously is effectively suicide.  If you can lure the fleet away from the starbase and fight them separately, that should work.  I'd also advise giving the bypass option a second thought.  Yes, it's a big deal to lose your antimatter and hull, but it's not an unwinnable prospect.

Generally speaking, if the enemy fleet is too strong to fight, they have starbases on their front lines, their empire and economy is bigger, and you don't have any aces up your sleeve, it's probably time to surrender.

ok, i'm tired of this cruel bs. it's always the same, no matter how many times he attacks and i destroy his fleets, he just builds a new one while hiding behind his impenetrable minefield+starbase defense which i can't breach without killing myself with upkeep. meanwhile im stuck with 5 planets and can't attack or go for the neutral system. it also doesn't help that my stupid flaks decide to drive into the heart of the enemy formation and my guardians are always out of antimatter or being crippled by cobalts.

In those big attacks I always have curtain ship types as a fleet. The first is carriers, always a separate fleet in the edge of the grav well already turned around ready to jump. Then the flacks as a fleet but follow the main fleet unless ordered otherwise. Even sometimes separating the repair cruisers in a fleet.
