Army of Darkness Defense is not your regular tower defense game, sharing elements with mega-hit Plants vs. Zombies (which, of course, isn’t your regular tower defense game, either, but it’s still included in this genre). Based on the 1992 horror comedy film of the same name, Army of Darkness asks you to play as Ash, an S-Mart sales clerk who somehow traveled back in time to the 13th century and now has to defend a castle from waves of evil undead. You can summon allies, use special abilities, and laugh at tens of funny quotes from the original film.

The original Bloons TD is a highly appreciated tower defense game, but it’s not free. However, Bloons TD Battles doesn’t cost anything to play – although, of course, it offers in-app purchases. Bloons TD Battles lets you play head-to-head with other gamers, offering 18 custom head-to-head tracks, 20 “monkey towers” (each of them upgradable up to 8 times), various achievements to claim, and lots of fun. The game has three modes: Assault, Defensive, and Battle, so you’re not going to be bored too quickly.

Since we didn’t include Kingdom Rush in our previous tower defense games selections, we’ll do it now. Seen by many as one of the best tower defense games available on smartphones, Kingdom Rush looks neat, has a great game play, and features with numerous tower upgrades with different abilities (to better help your strategies). There are over 50 distinct enemies to fight off, including hard to annihilate bosses. In addition to towers, you can use heroes to try and defeat invaders. Two paid versions of this game also exist: Kingdom Rush Origins, and Kingdom Rush Frontiers.
