Maybe I'm biased because this was one of the first games I've ever owned on the PS2 and it was such a blast to play through, but I thoroughly recommend this game, it is sorely underrated.
Surprisingly there very few pieces of media that cover an alien invasion from the perspective of the invaders, only this and Invader Zim (fans of Invader Zim will recognize the voice of Orthopox 13 as well), and that is so unfortunate because it's such a unique type of story, if you're bored to death of seeing alien invasion films from the humans' perspective and you just want to destroy everything; this is the game for you.
