There are three different types of economy structures available. They are very tough to destroy and can provide a place to expand your base.
Exchange - A small 1x1 house-like structure that provides a small bonus and an instant $100 capture bonus.
Commissary - A medium 2x2 office-like structure that provides a decent bonus and an instant $200 capture bonus.
Bank - Large 3x3 skyscraper-like structure that provides a hefty bonus and an instant $500 capture bonus.
Nice Yuri, looking great :3
Any Scorched Earth strategies involved?
Definitely. They're hard to take out but once you do, it puts a serious dent in the enemy's economy and base expansion plans. Garrisonable buildings will also be an important strategic factor in Advanced Mode maps.
