Fantastic game on it's own, but of course it lives in the shadow of something far better.
The Good:
+ Compared to a certain other game, I like the little differences. The special moves seem like a good idea but I didn't find them too useful. Being able to throw grenades on the fly is fun too.
+ The gameplay is actually quite fun and the different modes give it some replay value.
The Bad:
- Weapon Balance is off (more on this in suggestions)
- Damage is practically impossible to avoid. When you have a stream of melee guys (or zombies) coming at you and firearm mooks magically shooting through them, you have no choice but to burn a ton of ammo to kill the kamikaze baseball-bat wielding idiots just to get a shot at the gunmen.
- Medkits are way too random.
Suggestions:
* The pistol is as good or better than all the other firearms. I don't know why the starting weapon with the most plentiful ammo deserves to be so powerful. The Shotgun is just horrible, I'd suggest increasing the number of pellets to 4 or 5. The Assault Rifle is okay, but isn't really that much better than the pistol to warrant switching to. The Flamethrower is pretty beastly but runs out of ammo extremely fast, ammo is hard to find for it, and it's basically a melee weapon. In other words, it sucks too.
* Likewise, the Sword is actually better than all the other melee weapons. The Knife is just sad, the Baseball Bat functions exactly the same as the Sword, and the Axe is far too slow to be of any use (considering its the last melee weapon obtainable). Make the Knife the starting weapon, not the Sword. Nerf the baseball bat's damage a bit and make the Axe faster. This way, it would be Axe = Sword > Knife = Baseball Bat.
* The MAG Agent is pathetic for being a boss. He needs a lot more hitpoints and needs to swing his axe slightly faster.
* Medkits should not be as random as they are. A system like 1 medkit every 2 waves or X # of enemies on endless would've been much better. Considering how unavoidable damage is from the huge groups of enemies later, it requires some lucky Medkit drops to make it through the later waves.
Final Words: Great game that would've deserved 3.5-4 stars a few years ago. Unfortunately, since it's so similar to a superior game (Project Nexus, of course), the rating is hurt quite a bit.
Verdict: 7/10, 3/5
