Soldner-X 2: Final Prototype

This is a difficult challenge in which you must score 600,000 points within the time limit. You'll need to memorize where the clusters of enemies appear as well as the score bonuses from the breakable boxes. When you reach the first stopping point, let the enemies cluster so you can quickly pick them all off with the shockwave and keep the stage moving. Ideally you want to reach the second stopping point with enough time to kill one or both of the squidlike enemies with a limit attack (make sure you grab 3 special weapon powerups on the way). Another option is to try and kill all of the enemies at the first stopping point with your regular weapons. You'll have to be fairly fast in doing this or else your timer will expire before you reach the squid. Use your shockwave as soon as the first squid appears because at that point the timer will probably be almost up (this is the method I ended up completing the challenge with and I was just a few hundred points over 600K with less than a second to spare).

The Spread weapon is good for killing the sphere enemies from afar, but is lousy for everything else so be prepared to switch often. You get it along with the powerups in the beginning of the stage. This challenge's difficulty is fixed so you'll start off at a C (x20) ranking. Ideally you'll want to try and push it to B (x24), but make sure you never let it fall below C. I recommend using the Mexxus II alternating between the Spread weapon (for the spheres) and the magma weapon (for everything else).
