it's great addition to Mass effect 2 world.
anyway, the concept is, which combination with AI and human to create something horrible thing, greater than I thought before getting hand on it. 5 levels on one planet by hammerhead is bit boring. but I am glad to see some beautiful landscape through the playing. hammerhead still needs upgrade in terms of maneuverability. it is still the same like firewalker.
every level seems to be made very carefully. it is felt like playing original Mass Effect system even though I never played ME before (well, I watched youtube video so I get to know that combat system). combat is more dynamic, rich, and spacious. especially for the first mission. enemies are popped out not only from front but also side so that you have to watch, need to think more.
what I didn't expect is the last part. Shepard is suddely turned out like Neo in Matrix. I guess if I play Geth, the whole view looks like that. David is very very sad end. how can his brother just take him for horrendous experiment? of course, it's just a game. but this DLC tells us something to learn. now, we all know that Cerberus is not your side anymore. who know? if Illusive man thinks like that way to rebuild Shepard, he wouldn't be the same human anymore. I still don't believe that he is the same in ME2.
so next time when you go to suicidal mission, you must blow up collector base. don't listen to Illusive man. he is evil.
this DLC is worthy to pay $7. it's even better than Kasumi DLC. replay value? definitely no doubt. I highly recommend if you are a fan of mass effect.
