User blog comment:BestBMCplayer/How useful are the towers in BTD5, BMC and BTDB (flash)?/@comment-25404524-20170627102908/@comment-30336302-20170627103109

Sadly, I don't play BMC now:(

Yes.
 * Good cheap starting tower.
 * Cooperates with Farm.
 * 4/2 Spiked Mines is cheap and excellent for level 20 before with no help.
 * 1-2/4 Spike storm is excellent for late game.
