Pros:

-Very well made system for building
-Everything appears to at least work
-Intense action

Cons:

-Sometimes when hiring a survivor on Sandbox defense
the tower they are in will tip over
-Not enough to build on Base defense
-No infinite resources button on Sandbox Survival, which
calling it sandbox survival made me assume it would at
least have an infinite resource button
-Too many tanks

Conclusion:

This is a good pack with the best defense and barricade system I have seen yet, but it's still missing some things and as said it's not finished so I can't really determine if base defense is lacking things on purpose. For example there seem to be a few places that mounted turrets could fit but just aren't there. And to add on to that it's not very easy to barricade either. It's a fun mode to play for a while.
