Subs! Subs are now in PTE 77150! (UPDATE: 77238 hotfix)

It’s that moment that so many of you have been waiting for. Subs, absent since alpha, have made their triumphant return to Planetary Annihilation! Released into the PTE, Uber want you to play with them, experiment, and break them. See what works and what doesn’t and provide feedback.

Jables has posted that saves are coming in February and Galactic War is being worked on following that. Meanwhile tvinita will be looking into the orbital game soon after naval.

Design Vision for Subs

tvinita posted about his intention when adding subs into the naval balance:

SUBS! Okay, submarines. When designing the subs, I was trying to preserve what would make submarines strategically interesting within the current meta of the game while keeping them easy for the player to both understand and manage.


So, whatever way subs behave, you want them to be a pain in the *** for your enemy to deal with. To accomplish this, there is not a submerge/surface state on the subs. Instead, submarines are always considered “submerged” as you can see above. The key here is that though the periscope is poking up out of the waves, submarines cannot actually be targeted by conventional weaponry because just look at how small a target that periscope is–how are you gonna’ hit that with a broadside cannon? This forms the crux of what makes submarines a tricky target without making it too confusing or frustrating for the opponent who has to deal with them. While submarines have their own recon layer, it’s not set up in any way to be different from surface/air vision. So you can see the submarine, both visually and on radar (no sonar needed), but unless you have torpedoes, you can’t shoot back at it.

Terror of the Seas

Submarines are the cheapest naval units aside from the piranha. They’re relatively agile compared to ships, and they pack a lot of anti-naval firepower into a conveniently cheap package that’s hard to hit. A swarm of submarines will be an unprepared navy’s worst nightmare, and though narwhals now have torpedo launchers to defend themselves–stolen from the orcas–metal for metal, a force submarines will win out against a force of narwhals every time, leaving your submarines free to pick apart the rest of your opponent’s navy while you cackle maniacally.

Not the end-all of Naval Control

Submarines cannot be targeted by conventional ballistic weaponry, however, as of right now artillery and bombs can target submarines just as they can target ships. This is to make sure that you can’t just maintain complete unchecked naval dominance by spamming submarines and your oppponent has no options to counter short of superweapons, and to further encourage unit diversity. If you want naval dominance, you’re going to want a balanced force that can take on all potential threats to naval, rather than just building a unit that can maintain naval superiority while ignoring any other possible threats completely.

With that in mind, let’s go into the design of the two new subs.

Planetary Annihilation subs

Tech 1 Submarine — The Barracuda

The Barracuda is cheaper and more maneuverable than the other ships, and it’s packed with torpedoes that fire much more rapidly than the narwhal’s. It also has lower Health than other ships. This allows it to function as your basic naval superiority unit, as most ships can’t even fire on it and it’s the most cost-effective optionf or maintaining control of the seas against ships. However, since it can only use torpedoes it can’t do anything against land-based coastal bases like the narwhal and orca, nor can it defend itself against bombers.

Tech 2 Stealth Submarine — The Kraken

The intent behind the Kraken is for it to serve as a late-game raider of sorts. Basically, we have a lot of long-ranged and slow ships in t2 naval, and the Kraken is sort of the reverse. It has torpedoes equivalent to the Barracuda, but its primary weapon is its hailfire missile array, which is a shorter range bunch of missile launchers that serve very high DPS out to nearby enemies. Also, here’s the kicker; the Kraken does not show up on radar. So if your enemy isn’t scouting properly, a small crack team of krakens can be chewing through their base before they even know what’s hit them.

Subs are likely to change a lot over the next few days as they’re coming in hot off the presses, so be sure to play the PTE and provide plenty of feedback so we can make sure subs are at the best state they can possibly be when they hit the live build!
