Planet Killer v1.1.0 Patch Notes

Welcome back Commanders. This is our first major content patch since release and I'm excited to share it with everyone. I've gotten a ton of great feedback and suggestions for quality of life features, fixes, and things to make the game more exciting and continue improving the replayability. This patch also brings the new 2 player Co-op feature, you can play on the same machine with one person on Mouse and Keyboard and the other on a controller. You can also use Steam Remote play to try the mode with anyone! There's been a few new mechanics added, in addition to some balance changes. Leaderboards have been reset again due to this. The game should feel pretty fresh even if you've already put in 50+ hours so far, and with the co-op mode this should add endless fun with friends.

New: 2-Player Co-op

Take on the galaxy together in a new co-op mode, playable with Steam Remote Play. Each player chooses a ship, while both share an inventory, wingmen, and rewards. You’ll need to decide how to divide the galaxy’s resources between your ships, but together you’ll bring a lot more firepower to each fight.

Planet difficulty is increased in co-op, and the mode has its own leaderboards. Let’s see which duo can become the best Planet Killers.
