Kingdom Defence: Mercenary is one of the most addicting strategy games that doesn't require "powerful hardware" to play, but that doesn't mean that the game isn't worth the attention of those players who are used to massive, heavy games. The main task in the game is to place your fortifications and defenses with weapons installed on them. These buildings will guard the approaches, and with the help of powerful cannons, they will destroy all opponents who decide to attack your kingdom. Each wave of attackers will be even more aggressive and massive, so you need to take seriously the task of saving the kingdom. A variety of monsters will move in the formation of the enemy, and if you carefully examine them, you can meet, for example, orcs, trolls, goblins, and other terrible creatures that have never been friends with the human race.
