What do you need 14 weapons for when the game is over in like 15 min.The game way to short and saying that there's 2 huge cities to explore is laughable.
(Hint for final boss) Go inside the boss and use lightning gun right at the beginning it takes his life down really fast and then just use any other gun to finish him off.I was trying everything & this really did the trick.
lV 5 time for gold was frigging hard.But there was a glitch when i fought the boss and got a time of 1:48.77 I found out that R & M are best (Hint) stop and stay tight along the left wall first when you come in and hit the space bar like theres no tomorrow.
"The game in a nut shell" Buy only $100 turret guns until Lv 10.Sell all turrets & buy 1 laser gun on each floor.The unstoppable set up is 2 laser guns on each elevator & 1 power blast cannon.You'll have lots of cash to upgrade lasers and blast guns to lv2.
