To be honest, I have a mixed feelings about this game. It's even hard to convey it in my native language, let alone in English.
On one hand, Insect Armageddon feels like it wanted to give us something huge. Not just huge insect and robots and insect-robots, but also in terms of contents. Huge maps, destroyable building, neat variety of weapons, limited range of classes that compliments each other. But everything fell short. Not to mention you REALLY need to grind to unlock all the weapons, buy them, and fully upgrade the clasess. Everything just end up repetitive as hell. The "story mode" is pretty damn short too. Although that's not really a problem for this type of game since the main point is replayability. But the drive to replaying quickly died down when I'm slogging through same looking maps and same variety of enemies, hunting down mystery weapon boxes hoping 10-20 minutes you're spending would be worthwhile. Even though you could make a meal, go to ATM to pay some bills, clean your laptop or keyboard, write a blog post, shave, ♥♥♥♥♥♥♥♥♥♥♥ somewhere, stalk your crush, or simply masturbating to your lovely waifu in those time.
In the end of the day I still enjoyed it, but (while having no expectations in the first place) it's still kinda disappointing. Still, there's not much mindless murder simulator on PC aside from Insect Armageddon and Samurai/Dynasty Warrior. And having alien bugs as enemies does feels pretty refreshing, the only thing that could make this better if there's also bug-space-dinosaur enemies thrown into the mix. Not worth $10 though, but I doubt Bandai Namco would give a f-- I mean, give a price drop for this game. Or for their other "Westernized" game from their franchise on Steam.
I just bought it full price hoping for another PC/Steam release for their games. Preferably the "too-Japanese" one. I mean, Japanese devs with or without the help from small US publishers are starting to flock into this damn DRM platform, right? And they did put a translated rhythm game and one single album to US/International iTunes, right? There is always hope, right? RIGHT?
