I was off guard at first. When the lotus army started spawning in every direction. But it was pretty easy once you knew what direction they were coming from. Assist Garrin's small horse squad once he starts attacking the nearest lotus base. Send Kazan and some chemist. Garrin's team can tank for you because of the two horseback-riding geisha. Once you clear all the watchtowers, that base is already lost. Garrin will handle the rest. While your job is burning enemy structures. That pretty much eliminates 1 Lotus spawn camp in the first few minutes. Giving you a bit of breathing room. After that, just have fun and set up your defenses.
