Very few units can be placed in water directly, and the night stages with water can be problematic. This extra cost of Sun Points is designed to dick with your resource management and to frustrate construction. The water hazard introduces the dangerous element of placing an extra unit on a water cell before a unit can be placed on it. Rely on the cheaper units and cover their limitations so they will work for you. Keep in mind that you can still build day (flower) units, but for the most part, you operate with a different set of gear.
Since there are no free sun points dropped in night stages, you use the cheaper but more limited mushroom units. Night time will affect your resource gathering. Note that a zombie can destroy your grave buster if it is close enough. Use the Grave Buster unit (a one use unit) to destroy head stones and make the cell a plant friendly spot. You cannot place units there, but you can expect zombies to spawn from them instead of just off the screen. Head stones are occupied cells during nighttime. You will need to be selective about your choices late in the game.Īs you progress deeper into adventure mode, other conditions will occur that will make you change your tactics, although the strategy will be the same.
