Not seeing the update?
Steam doesn't usually inform the player right away of the update, they tend to wait until you restart your Steam client or until a bit later after the update has come out. So if you want to get the update right away you can do the following:
- Right-click the game in your library and select properties
- Go to "Local Files" and click "Verify integrity of game files"
- The game should immediately start updating!
Update 4.0
This update brings a completely new game mode to the game as well as two awesome maps for it! Along with that are some interesting new features, and fixes for several commonly reported bugs.
Infinite Waves
If you thought you had it rough before then wait until you see this. The attackers are now working with an unlimited supply of units to try and take you down! Every 10 waves they learn from their mistakes and get stronger. In this new mode there is no attacker, play with up to 5 defenders on brand new maps made for this new mode! How long can you survive?
New Maps
Two brand new beautiful maps are here for the Infinite Waves mode! One of these maps is DLC-exclusive, but non-DLC owners can still play on them if someone with the DLC hosts. So if you own the DLC & want to play on the DLC map you can still play with friends even if they don't!

Broken Pass
You were taking a transport when there's an explosion. What do you do when the only exit has been destroyed? Fight until the very end on this intense 2-side attack map!

Braunschweig
This was once a quiet & peaceful city in Germany. Now as the war rages on the city is under siege by enemy forces. Battle at the outskirts of this great city and defend its name!
Other Changes
New Features
- Rooms can now be given a password when created
- You can now see the health of all defenders
- Added muzzle flash to guns
- Added bullet impact effect
Fixes
- Fixed turrets not giving materials if the owner died
- Fixed Oceania region not working
- Fixed stunned units having a 0% chance of playing the death animation
- Fixed attacker camera moving while typing
Conclusion
This update adds an awesome new mode which allows for a more intense and rewarding experience. I'm also happy that a big bug was fixed (Turrets not giving materials on death), and that a big feature request was added (password-protected servers).
I wanted to add singleplayer to the game for the new Infinite Waves mode but sadly that ended up requiring more restructuring than previously thought which wouldn't make it possible without a large time investment which would take away from working on other things.
Overall, I'm really happy with this update and I think the new mode really helps add to the game, especially since you don't need other people in order to play it.
Sincerely,
Blake Gillman
