  Planet Killer Releases September 9th — Thank You for 6,000 Wishlists!

  Hello, Planet Killers!I wanted to make a more personal announcement as we get ready for launch and say thank you to everyone who has played, wishlisted, followed, shared, streamed, reported bugs, filled out feedback forms, or simply kept an eye on the game.Planet Killer has now reached nearly 6,000 wishlists.That's a milestone I am tremendously happy to see as we approach the full release on September 9th.During the playtest and demo, I also collected nearly 100 player feedback submissions through Google Forms.

Weapons, passive cores, modules, and basically all other systems have been adjusted significantly based on both player feedback and the data I've gathered from the demo but I haven't changed the core of the game, because it should be brutal sometimes, and it should be exciting sometimes to get a really good weapon.The Wingman system has also been improved and is now communicated much more clearly. Wingmen can equip one weapon and one passive module, opening up even more possibilities for specialized fleets and unusual builds.And all of this is really what Planet Killer was designed to be:Giving you systems, tools, and ridiculous amounts of firepower, and seeing what happens when you combine them in the face o...
