Good, overrated
I always feel kinda harsh reviewing the highly rated games. If this had scored a 3.something and not got a lot of attention, I'd be giving a rave 10/10 review here. But as it's the #1 game currently, I'll be more critical.
I'll start on a positive note by saying that it looks fantastic. Graphics as good as these are rarely seen in movies, let alone games.
The game itself, mildly entertaining, but nothing special. The concept was very unoriginal, can't keep count of how many base defense games I've seen on Newgrounds. The upgrade system of using a given amount of hours to search for weapons and survivors was a nice touch and something I've not seen before, but didn't do much to change the gameplay itself.
The game mostly just involved basic pointing and clicking to shoot. Although the character could be moved, this didn't serve as much purpose as it could have. I'd have liked this much more if the character wasn't refined to one area and movement was more essential.
It also got far too repetitive. The enemies changed slightly over time, getting a bit faster and wielding weapons, but I was always waiting for something really exciting to come running towards me. The background was one of my main problems with this, looked great, but didn't change nearly enough. Would've been better if the team had found better vantage points as the game progressed.
Nice array of weapons, but the system could be better. Why couldn't teammates be equipped with weapons not in use? Also, I'd have loved to see grenades here, but didn't unlock them in the time I was playing (can't say for sure that they weren't one of the late weapons though).
The game lacked story too. The occasional cut scene between rounds would have really brought this to life.
I think this game is proof that a game that impresses players in the first 5 minutes will score well even if it doesn't amount to much more after playing for a while. Definitely has the potential for a sequel, try and veer away from overused ideas and add some more original ones. This shows that you're one of the most talented users on Newgrounds, I hope you manage to realize that talent to its full extent.
