a simple walkthrough....
i can say i beat the game (2:22 seconds) and here is how you can too!
this will be broken down into the 4 sections:
section 1: missiles. simple loop around them and after a few seconds they auto-explode. rinse, recycle, and repeat till the section changes.
section 2: lasers. this one is a bit tricker so practice and follow the guide as best you can.
shot 1: get in the middle all the way in the back the lasers will be above and below you. when the lasers fade time to move.
shot 2: go either above or below (i recommend above) and as close as you can to the machine. there is a very small sweet spot where you can shoot the machine with both the gun and missiles. when the lasers fade get back to the middle, all the way into the back.
shot 3: this is a 4 part shot so be careful. part 1 the bottom laser cuts down and the top laser does not move. move down with the bottom laser. part 2, the top laser closes in behind you. part 3 the top laser moves to the top of the screen. move up with it. part 4 the bottom laser moves up to trap you inside. again there is that small sweet spot where you can max out your damage on this section.
section 3: shoot and follow. this section will shoot at you where you currently are. meaning if you move, that shot will not hit you. be warned, this section will keep shooting at you. keep moving (sometimes ducking through the shots) and you will be fine.
section 4: big laser. this is the easiest of all the sections. just duck to the top of the screen and keep shooting. as the laser fades duck down to lay on the damage.
now that you have gotten through all of those sections, back to the first one. here are the differences when in the second wave. in section 1 the missiles linger around longer, not a big issue except when going into section 2. in section 2 the lasers follow the same pattern, only much faster! so get to your safe points quick. section 3, the bullets are closer to each other. harder to get through them. section 4, no change, still a big laser. if you defeat a section, it will just be skipped. i dropped them in the order of 2,3,1,4.
hope this little walk through helps you beat this tough game!
p.s. if you found this helpful or something you would change in my descriptions, send me a message so i can better describe these games in the future! thanks!
