overall good.
I found the gameplay good, fairly smooth, and with no major problems in te character itself or any of the weapons.
Others have complained about the character's slow movement, but i didn't find that much of a problem.
Someone said that they had to use up all their ammo shooting open the doors, but there are ample keys lying around everywhere.
I only have 2 major problems, and 1 minor one.
2 major problems: 1: the CoD influence was obvious and i think the rank system is good, but please, for the love of all things good and pure, get rid of the china lake. 2: The story was far too easy. all i had to do was get the fmj and rapid fire attachments on any weapon and the aliens would fall like matchsticks. on the basic assault rifle, with rapid fire, the knockback effect on the aliens is strong enough to stop them from moving at all. Minor problem: on the night vision level, sometimes one of the tiny aliens would manage to charge right up to me, and then i wouldn't be able to see it at all because of the light in front of the character. this lets them drain about half my health before i realize what's happening. One last thing is that this felt a biiit too much like a kind of DeadSpace Lite, what with the writing in blood and all. Overall: 9 for gameplay, -1 for the easiness, -1 for the china lake, -1 for the DeadSpace lite and the tiny aliens, and +1 for the smooth gameplay. 7/10 4/5
Also, a suggestion for the next game: make a menu with subfolders for the challenges. It takes a little bit longer than i'd like to find the one i'm looking for.
