It should be yes, I have used it since 1.0 came out successfully!

is that sub still playable?

Thanks for letting me know Imaxium! You were right, it was not working after the update. I've fixed it now and it works again, hopefully I've updated it correctly... It's the first time I've used the new system.

I think the wifi on SRR Drone is broken with latest update, or am dumb and dont get how to use. Couldn't figure out how to load drone into editor to inspect, so leaving a comment here.

Alright, glad I could help. Regarding the ballast-tank issue, what I noticed is that it was usually bots with repair-systems orders that got stuck in the ballast, which makes me think they were either heading there to fix the pump or they were taking a stupid route to go fix something else.

As for the oxygen, it is partially by design, though going by your description I think the last update to oxygen generation may have thrown it a bit out of wack. The drone control room in the Palestar A is not really designed to be closed while in use, the door is mostly there to let you close off that area in-case of flooding. The subs are supposed to have enough oxygen generation for a small crew but as the crew grows you will need to upgrade the oxygen generator. If you are still having oxygen issues after getting full upgrades that is not intended. I'll increase the initial oxygen generation for the Palestar line to try and help curb this.

Thank you for the feedback on this sub! I have considered setting up periscope movement controls for the drone, but it is pretty complicated to wire up and I haven't had the time to look into how to do it yet. I don't think it is currently possible to set up sub controls to work with WASD, hopefully that can be a thing one day! In regards to the forward ballast issue, I've noticed the bots will sometimes hangout there for no reason just walking into the left wall. I've double checked the waypoints and there aren't any going through that wall so I'm still at a loss as to why this happens. Right now if I notice somebody in the ballast for longer than they should be I'll just switch over to them and walk them out manually, though I can see this option not working for multiplayer. I believe you can just order the bot to follow you and then cancel the order when they get out of the ballast to deal with this in multiplayer. I'll keep my eye out for this issue and try and get it resolved.

That said, I did discover two significant problems with the Palestar A, one of which might be intentional, the other of which certainly was not. The bots constantly got stuck in the front-bottom ballast tank, eventually drowning/suffocating. I could find no rhyme or reason for why they kept going there and mashing against the leftside wall of the ballast, but they did. It's a big problem.

Second, oxygen generation on this little sub is... problematic. All of the Palestars have this problem, so maybe this is intentional, but I had rooms becoming deoxygenated just because one person stood around in them. The shuttle-control room is by-far the worst for this; just standing there using the drone control terminal will kill you. If that's an intentional design flaw, it's pretty funny, I'll admit, though I am getting a little tired of transport missions failing due to rooms deoxygenating on the Palestar II despite full oxygen upgrades.

I took this little number out for a spin, and I got mixed results. First off, the camera drone is hilarious and fantastic; the only thing I'd ask is to implement a Click-To-Move function for its cameras (other drones on the workshop have this functionality, allowing you to move them by clicking while in periscope view; using WASD would be even better).

As for the sub itself, I was pleasantly surprised to find the aggressive gun placement is actually better for an experienced captain, just as the description implies! This ship is so agile, it was easy to constantly hold the enemies in the vicious crossfire sector of the two coilguns and mow them down. In terms of performance characteristics, this is definitely the sub to take if you've got an ace captain looking to get away from the Palestar I's newbie-proof gun placement that doesn't allow focus-fire.

Thanks

My bad, I must have accidentally set the periscope to hidden with my last update. Should be fixed now.

i can't use rear coilgun

That's what I like to hear! Glad you are having such a great time :)

Great compact sub! This was my entry level vessel for single campaign...but after this, just another Shi Jie product could fulfills my expectation.
