The tower defense game genre is quite popular and easy to get used to. You will need to set up your defenses as solidly as possible, then face a series of enemies attacking from multiple directions.
Games are usually played in levels, and after each level, the enemies will become more aggressive and numerous, while you will also have better weapons to take them down. Although this genre is often found on phones and tablets, there are also many excellent tower defense games on PC. Here are the top 10 tower defense games of 2021 for you to enjoy.
Anomaly: Warzone Earth
Anomaly: Warzone Earth can be described as a complete reversal of the tower defense game concept. Instead of just watching and placing units on the map to shoot at each other, you will directly control a specific unit to sneak through enemy defenses.
After breaking through the alien invaders’ defenses, you will need to keep your units’ health in good condition and upgrade them whenever possible to ensure the mission’s success.
Of course, you will encounter quite a few enemy defense towers along the way. So get ready, because this is not an easy game to play.

Orcs Must Die! 2
The Orcs Must Die! series blends third-person shooting, melee combat, and magical combat in a fantasy tower defense style. Therefore, the game requires players to combine strategy with skills to defeat the orc hordes, rather than relying solely on weapons or traps.
The orcs will become more aggressive each time you upgrade your weapons and traps. Additionally, the fun fantasy elements inspired by the game Magicka combined with the co-op gameplay have made Orcs Must Die! 2 more appealing to the gaming community. Part 3 is currently exclusive to Stadia, and we hope it will come to PC in the near future so fans can continue battling those wicked orcs.

Iron Brigade
Developed by Double Fine – the studio famous for the hit game Psychonauts – Iron Brigade is unfortunately not very well-known among gamers. It belongs to the third-person mech combat genre blended with tower defense mechanics.
After World War I, a mad scientist devised a plan to manipulate the world with a deadly TV army. Fortunately, a group of heroes rose up to fight against this scientist, restoring peace to the world.
Players will control heavily armed robots while also setting up defense systems to fend off attacks from the Tube. Unique gameplay, co-op mode, and the humorous touch typical of Double Fine are the highlights of this game.

Bardbarian
In the game, you play as a barbarian named Brad who has “hung up his sword” and decided to play the guitar. By doing this, Brad can summon fighters to gather around him and attack any enemies that dare to come close. This is a tower defense game where the defense will follow the player on the battlefield.

You won’t need to lift a finger; just lead your soldiers, strum your guitar to boost morale, and collect coins to upgrade new soldier types, new boosts, and unlock some interesting characters to help you balance the battlefield.
Rock Of Ages 2: Bigger And Boulder
The Rock Of Ages series is a rather interesting tower defense game. Each level features a long slope running down a hill, with a base at the end of the road that players must protect at all costs. Meanwhile, your opponent will do the same.
When one of the two is ready, that player can control a boulder to break through the opponent’s defenses, smashing their base to pieces. Of the series, Rock Of Ages 2 is the best installment, as part 3 is quite difficult and therefore less enjoyable.
