Superb environment, so-so gameplay
Not enough space to fit all the shyt I want to say, so you're getting mostly criticism instead. Ahaha! I understand that this is a fairly new game on newgrounds, and that it may go through revisions and improvements later, but I'm making my review now.
Difficulty-wise, your main danger in the first couple levels is running out of ammo for the assault rifle. I kinda wish I was prompted about how to swap weapons earlier (I may have missed it), so I don't waste ammo on the small fry.
Radar sucks. It takes too long for each ping to happen to make it actually useful in the residence floor (the only place where I seriously considered using the radar), where it would have really made an appreciable effect. Nope, turns out the time I used to stare at it ended up with me dying to lots of large aliens while hacking a door. I have not made that mistake since, due to its utter uselessness. Oh, and it doesn't detect the surprise-buttsex black aliens that like to hide in the shadows, but I have to applaud you on that instead.
The first time the small aliens busted out from grates, the grate itself was being pushed by the aliens, which in turn shielded the aliens from my gunfire, which in turn led to me dying from the combination of alien love and sentry fire. Fun. Geez, if you wanted to give them shields, make something more believable. Or, you know, make it so that they can't use grates as shields.
Speaking of grates, the regular holes you see aliens crawling out of somehow act like walls when you're trying to get somewhere. This is pretty irksome, especially in the final fight against Strix, because you can't exactly see those dumb holes so well, and you take a projectile in the face. Either that, or the protagonist has an extreme phobia of getting his ankle busted, but I refuse to believe that when death has even worse side effects.
The sentry guns have some aiming issues. I've noticed that during certain times, they point slightly to the left or right of you. Further playing around with them revealed that I could stand right in front of some of them and they wouldn't be able to shoot me because of faulty logic or something. I dunno.
There's only four types of regular alien baddies in this game? That makes swarm mode insanely boring to grind when you're going for the challenges. And the amount of grinding it looks like one has to do to complete all the swarm challenges is akin to nonstop monster slaughtering 24/7 in some generic grinder MMO (classic MapleStory pre Big Bang if you know what I mean). This is not fun; this is unpaid work. Sure we're not obligated to do it, but the point is this is stupid.
Also, because there's so many mobs in the later waves of swarm mode, the free supplies you get from time to time hardly cover your needs, so the best tactic may sometimes be camping next to the shop and buying whatever you need. Okay, fine. What's not fine is taking 3 seconds (5+ during lag) of staring at "welcome to HAVEN Supply Network" every single time I want to refill my ammo. Compound this problem with the fact that your ammo capacity is pretty low, and it's even more "hai gaiz welcome back to the HAVEN Supply Network!!" First time using the shop, I was like "ooh pretty" and it was cool and interesting. 30th time is more like "HAVEN SUPPLY NETWORK OMGZ!!!!p0rn!!!" Forget owl men, the Haven network has its own subliminal messages agenda.
I hope I'm being blind or something, but no options? Sure there's the right-click menu during the pre-loader, but I don't think that actually has any effect once you get to the menu screen. Like, what if I don't want the game to lag horribly after painting the floor black with green blood during swarm mode?
Why the insanely high negative numbers after you complete all the levels of a particular challenge? The programmer side of me knows what it means, but the gamer side of me says it's somewhat nonsensical. I mean, -2500% after you finish killing X amount of monsters with the pistol?
Good job on the gfx. Chalkboard screeches from alien aggro in swarm mode.
