Strategy: Get Pure Attack for Warriors, and Mages, Pure Push and Attack for Spearmen. Get increased maximum mana and regeneration and all bombs. Then simply spawn all your troops in one spot at the beginning
and use all your bombs but fire and ice on the corresponding spot of the enemies. Then charge through without contest. With the high attack and push of your troops, the enemies' life will be gone before they even reach your side.
Here is a trick for "Unscathed" for the first boss, as the boss appears, quickly destroy the center armor plate, then run up at the edge between the middle gun and the side gun, the boss will never be able to hit you again, and you can shoot it without risk.
Extremely fun game, however, once I learned a mage strategy against "starred monsters" it became easy. Just keep using Ice Nova, and in between use Firespray if you have it, immediately after Firespray use Ice Nova. Firespray will prevent the enemy from attacking until a second or two after, which is enough time to use the ice nova knockback. Using this strategy I never put had to put any points into health increasing stats.
I see!!! so the developer is the king hamster!!! Since he created the achievement system to make us feel good for ourselves when we did something. (^_^)
A bug, when picking up rare units with full unit capacity, a box will appear saying that the rare unit is added to the inventory, but it isn't however.
