Online multiplayer, demo version, and more!
Dual Core Patch Notes — September 16, 2016
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
The latest update includes online multiplayer. It's still in BETA, but now in the main version of the game (not the beta branch)
There's also a bunch of other fixes, including improved mouse/keyboard controls (popup inventory on RMB, so no more awkward key combinations!). We also speeded up projectiles a little (by popular demand!)

For those still on the fence, a free demo version of the game is now available - click the "Download Demo" on the store page.
Last but not least, work continues on a brand new game mode, featuring procedurally generated levels. Not 100% sure yet when this will go live, but hopefully it will be something that will see ongoing updates, with new content and features. We'd love to hear feedback on the kind of things you'd like to see in this game mode.
