Undead Invasion

Undead Invasion is a 2D tower defense game where players control a hero who they must help fight the hordes of zombies. Luckily, your hero won't be alone, as they'll have the help of loads of other troops that they can recruit throughout each level. Without the constant support of these troops, it will be impossible to win.

The gameplay in Undead Invasion is simple and the controls are very easy. Basically, you have to go about recruiting troops to defeat your opponents before they defeat you. You need money for this, which you can automatically get each second. As usual, the more powerful troops will be more expensive, but the most important thing is to learn when and how to recruit each type of help.

Undead Invasion's single-player campaign mode has dozens of different levels that progressively increase in difficulty. Luckily, each level you pass will give you skill points, which you can use to improve your troops' attributes and even recruit new ones. For example, at the start of the game, you only have low-level soldiers and ax throwers, but later on, you can recruit archers, Vikings, wizards, and loads more.

Undead Invasion is an excellent tower defense game with role-playing and strategy elements and a wide variety of heroes, troops and levels. The game also has a charming retro aesthetic that older players will definitely love. These players will also like the game's difficulty, which is significantly higher than other games of the same genre.
