Well, after much gaming, and plenty of time taken, i have reached this. Post pictures of your scores below if you want to compare
With all due respect, I'm not hating. I simply find the circumstances suspicious, for reasons outlined in my other posts. Given how easy it apparently is to manipulate the save file, I have good reason for questioning its authenticity.
The only type of enemy he would not of faced in the previous Titanium high score he made it to would of been the Mark 2 Jetpack Robots and since they get stuck easily it's not super hard to kill them.
Correct me if I'm wrong, but I believe Spider-tron 6000 also only appears in Titanium difficulty, and, later on, in greater numbers.
Having said that, I've spent probably around an hour in Titanium mode, and I have yet to see a Mark II Jetpack Bot get stuck. Most of the levels I've seen them in have either no walls, or thin/limited walls, meaning they have a straight shot to you. What's more, in the numbers they appear in, trying to deal with a pack of them head-on will almost always result in your death.
So, in summation (and to reiterate my point), I fail to see how someone who had only encountered the two aforementioned, exceedingly difficult enemies once or twice could have survived through 10-15 waves of the things, especially when they've only gotten about a third of the distance twice before.
Spidertron 6000 appears in gold I believe. The jetpack bots get stuck on the walls by the elevator while jetpacking which allows for easy kills. It is possible to do just difficult and needs a strategy for each level.
