I just can join Draco18s comment there, normally did i think Kongregate is a free Flashgame site, but i hardly can enjoy this without subscribing, and i dont mind paying for flash games normally..
I personally have nothing against the Payment system but i really wish i could use the circuit system just halfways, :/ , also it reminds me pretty much about Super Metriod but the gameplay seems to me rather dull, the coop system is also nothing special. i give it a 3/5
Campain is abit rushed made, and also Team AI's are sometimes way to retarded . besides that its really unbalanced one time its really hard the other time its to Easy, for example the Mission with the Zombies abboard the ship its most likely impossible because they can take alot of hits.
Less of a game :x Could have done better as animation, also might want to take few grammar lessons XD, also, The art is really nice and intresting also the animation, but kinda as game, is it horrible without the story. there is actuallity like no gameplay.
Nice Art for sure but about the story am i abit dissapoint, i hardly did understand what at the end really happend beside that this could have done better as animation then a game
need to take it back, that game needs major balancing, the aliens have way to many adventages , for example the ranged flying ones can take out turrents easly, the big artys are really hard to kill and deal alot of damage not to mention that the humans have hardly any tactical points beside shooting all the way upwards, which is completly useless because the damage isnt high enought
