5. Destroy All Humans! (2005, PlayStation 2/Xbox)

Though it may not stand out in terms of scale - hey, it's one alien! - Destroy All Humans! offers one thing other alien invasion games can't quite match: you're the alien. Playing as Furon clone Crypto-137, you take to the Earth to molest, explo🌠de and harvest the DNA of the entire hapless human race.

This blend of 1950s sci-fi kitsch and high-powered, free-form action is certainly the m⛄ost amusing alien invasion on our list. When you're using your anal probe to burst the heads of happy Americans and extract their brain stems, you'll realize: being the invader is as fun as repelling the invasion.
