One of my favourite games, kept me entertained for ages.
Dungeon Defenders is a tower defense game where you play with 3 other people (Or by yourself) to defend the Eternia crystals.
What makes this game more fun than some ordinary tower defense game is that its creative. There are many different characters each with their unique towers and abilities, (Except the hero's from the more heroes pack.) many different maps and challenges, many different enemies and many different equipment.
It can get boring if your stuck at a specific point.
Not many people play on it these days.
Easy to suck the game dry. (Not in that sense)
Other than that this game is very fun, but its more fun with multiplayer. 10/10.
