This is a genre I like and usually I play this kind of games in their flash/java online version but there are some nice Tower Defense games that can be downloaded and installed on Linux systems, today I’ll present you 3 of my favorites: Creeptd, Target Defense and Revenge of the Titans
But first a small introduction to what’s a Tower defense game:
The goal of tower defense games is to try to stop enemies from crossing a map by building towers which shoot at them as they pass. Enemies and towers usually have varied abilities, costs, and ability costs. When an enemy is defeated, the player earns money or points, which are used to buy or upgrade towers, or upgrade the number of money or points that are earned, or even upgrade the rate at which they upgrade.
