Kingdom Invasion: Tower Tactics is a free to play browser, online 2D RPG. Your mission is to defend the Kingdom from the orcs, build and upgrade your towers and recruit powerful allies. Combat is quite fun, graphics are great adopting a cartoon-like look & feel and animations are well crafted.The gameplay mechanics offer an extended scope and replay-ability to the game and new gameplay difficulties can be unlocked. Core strategic element to the game is to properly select, position and upgrade your towers in the map, in order to gain a battle advantage and defeat the orc enemy waves. Tower options include ranged attacks, area damage attacks, spell attacks or barracks to order knights’ intervention. Along with spells and heroes, the available combat arsenal you have at your fingertips to choose from, is quite varied and strategic, although the game progresses in a linear path.Fact is that this path along with the quite restrictive progression system that requires the use of “Energy” for most actions and the limited effective ways to replenish it so you can keep playing, absorb a great amount of enthusiasm as the only way to avoid waiting and progress, is by spending, quite frequently, real cash. Finally, for those seeking out an Arena, it is available in-game for PVP battles, so they can match their strength and test their skills versus other players.2D Browser MMORPG
