The first official expansion to Defense Grid 2 is now available - just a few(!) years after DG2's launch!  

These new advanced levels continue the campaign and begin right after Chapter 5 (which is likely where the game puts you if you've finished the original and start it back up). If you purchase Aftermath, just hit that chapter arrow to the right in the Campaign to take you to the next new Chapter and continue on in Aftermath. The story continues onward.

DG2 and the Aftermath expansion now both have full voice localization for English, French, German and now we've added Simplified Chinese, Spanish and Korean as well.

Aftermath was previously released for Defense Grid on the Oculus Rift and Nintendo Switch, but hasn't been made available on Steam until now. We hope you enjoy it!

Defend the Cores!

DG2 got an update today, in 2026.

• DG2 now has full VO audio for Simplified Chinese, Spanish, and Korean!

• The DG2 Special Edition now includes the official Soundtrack (you get it automatically if you already have the Special Edition or the Special Edition Upgrade)

• If you just want the Official Soundtrack, you can now buy it separately as well

• Several edge case bugs have been fixed from launcher issues to visual bugs, to supergrinder memory bugs and other rare crashes.

• Oh and the game is now prepared for a new DLC called Aftermath! (coming soon)
