Looks like it's like last time.

The updates with mini campaigns. Only this time the wait is longer. Updates will be on last weeks of December, January and February. :(

Oh well, it's probably worth the wait.

Thanks! I was looking for the release schedule for the next updates but couldn't find them.

I reached the final level yesterday and the game felt so short (but still awesome!). Looking forward to the extra levels. Also looking forward to Kingdom Rush Vengeance, hopefully the PC version won't take forever to be released.

Finished it. Going to play Iron and Heroic (finished those for first campaign too).

Lovely. Simply lovely. Worth every penny of buying as soon as it comes out on full price. Looking forward to the extra campaigns.
