Grim Defender - a hold strategy.
Do not confuse two similar, but at the same time, a different genre. Tower defense, it’s also tower defense, is a strategy where you place towers along the way the enemy moves. In the "defense of the castle" your task is to shoot from the endlessly attacking waves of the enemy, strengthening the fortress and its towers. In Grim Defender, in addition to traditional crossbows and cannons, magic spells, traps and other abilities await you - use everything that no enemy has passed through the royal gates.
