President's Escape Pod

During this mission,you always want to take the path with GUN robots. Always try to get the guns with 30 bullets but if you beat the whole thing and have the Shadow Rifle,use that instead. Using the Shadow Rifle can do some killer damage that will destroy the escape pod within at least 12 hits. If you use Chaos Blast,it won't always hit even though it does less than adequate damage. Turrets do some good damage so try to use that whenever possible.
Side Note:If you have The Ark Stage,just complete the Dark mission and you will get to the Pure Evil stage quickly.
Hope this helps.

When you get it on the path that has GUN robots, keep following it and keep firing. Remember, when your in Chaos Control or Chaos Blast mode, if you haven't used them, you can shoot without using a single bullet. Use that to your advantage. Try not to use Chaos Blast, because it probably won't hit. The pod will just keep moving, out of range. Also, try to pick up really good guns (ones that hold 30 bullets per magazine are great and abundant), and finally, use turrets when you can. Those are very powerful.

Any Weapon just keep attacking like nuts. It should soon be destroyed.

Get it on the path with the GUN robots, and shoot it with te guns from the robots, and if done correctly, one of the wings will blow up right before you go inside from the first grinding rail when the say something about the sunset.
