Brilliant!!!!
Okay, this game was just great and I played it for a hella long time so I'ma give this game a good review.
Graphics: No flaws there whatsoever, loved the screen shaking effect and the blood and how the bodies blood and bullets stayed. It didn't bother me or lag on my computer (because I have a Intel Pentium D Dual Core Processor) so I thought the graphics were great.
Style: The style of this game was really great, I love how you did the zombies and everything. The Spider-Man suit was kinda ironic too :D. I loved the weapons and upgrades that you put in there.
Sound: The sound was great but I don't know if it was in sync or not, but it might be my speakers. Otherwise perfect job on all the sound effects for the bullets hitting and killing the zombies, and just the gun firing whatsoever.
Violence: Oh my god, so much blood.....I loved it! I really love the way you did the blood, you really introduced a new level to zombie defense/survival games.
Interactivity: The aiming and reload and everything else was top notch, good job there.
Humor: The funniest thing was the Spider-Man suit, I'd have to say.
Tutorial: Okay, I am going to give everyone an easy tutorial to the defense mode of the game.
1st off: Keep the pistol until you get enough exp to get the first magnum, then kill until you can get the street sweeper. The street sweeper (1st automatic shotgun) will do you good until you get enough exp for the USAS 12 (The second auto shotgun) and once you get that, get enough exp for overkill then get 3,000 more exp so you can get the laser gun. Once you get the laser gun and kill monsters with it you will be swimming with exp and you can basically get all the guns you want and be undefeatable. Thanks for reading my tutorial....I hope this helps a lot of new players!
