Not bad, It deserves a real review (spoilers)
Presentation - 8.0 : A pretty solid 3d shooter built in Flash. Going in, my expectations weren't the same as they would be for a 360/Wii/PS3 game. However, it certainly surprised me.
Graphics - 6.5 : As I said, I didn't have very high expectations, but it did surprise me. I did not know that Flash was capable of such graphics. On the other hand, there were some tricky parts. Such as the forest area, after you escape the pipe cleaner. The ground looked really glitched, and I thought that something had messed up.
Sound - 8.5: Probably the best part of the game. It certainly enhances what was going on. It did sound sort of... generic. Don't get me wrong, though- it still had a sort of epic feeling to it. The voices were slightly campy, and after a while, they cut out completely. (It may have just been me, though)
Gameplay - 6.5: While it feels like a first-person shooter, there are some parts that feel like they don't really belong. The third-person view didn't really seem necessary. The heal system, while handy to have around at all times, was flawed. When I tried to heal, it seemed like the healing unit was trying to escape; it was rather hard to get a hold of it, even escaping my grasp after I clicked on it and held it. The chemicops were rather annoying, hopping around a bit much, and sometimes, hit detection seemed way off. I must have fired 30 rounds into one enemy, and not a single one hit. There are merits to be had, though. The achievement system is likely to bring a few people back to get the best achievements possible. The story has real potential as well. Being only about a 15-minute game or so, it could definitely go a lot farther.
Lasting Appeal - 6.0: I feel like it really depends on who is playing. I think that since there is a real game here, that I could come back and play it again, but I'm not so sure about how many times I could play through. It does needs some work, but there is enough to merit one whole playthrough at least.
Overall, a 7 out of 10 (not an average).
