PLEASE STOP BUILDING BASED ON THE RECOMMENDED PROJECT. Always check the D2N forum thread instead.
It's very often wrong and once it gets set to something it's a pain in the ass to get it changed. The correct build order is in the forum thread. Slip 'n' Slide is one of the worst buildings in terms of APEF efficiency.
http://goo.gl/ZWYFYis a spreadsheet I made with all defensive buildings broken down by APEF and availability, if you want to see how I pick the build order.
Edit: The recommended build is correct again. Spirit Mirage is what we need finished before the attack today.
Site is up but I am missing 2ap, the 2ap I was saving to get into town. I need either an alcoholic drink or I have 2 unlabelled drugs on me but don't really want to risk it. Thoughts?
