GPT: "Earth Defense Force is a long running series most popular in Japan. For some time it has occupied a rather niche following in the US, and for the first time a game in the series has been developed by a Western studio. Earth Defense Force: Insect Armageddon was made by the guys behind Eat Lead: The Return of Matt Hazard and more recently Matt Hazard: Blood Bath and Beyond. That might be a potential warning label for you, but I still recommend giving the game a try at it's budget MSRP of $40.00." 6.0/10
Sp campaign a 5, get real play on inferno or hard, for some replay, there is enough lvls so stop selling it short, it's not a 10 but isn't a 5 either.
One reasonable thing you did say was more dlc hopefully, i have spent more hrs on this $40 game than several $60 i have bought.
Btw since inferno difficulty maxes out at 8, where did tier 9 come from.
