Given the
recent publication of a second TAS for Arcade Mode (which obsoletes the OP's movie), I'd like to ask if anybody's looked at the
Advanced Story Mode which is unlocked by clearing Arcade Mode.
I'm not exactly good or efficient at TAS'ing games (hell, I still have trouble pulling off a no-damage run), but here's my thoughts, level by level, for Advanced Story:
1: not a problem, just make sure you get the headshot on the boss on screen 3.
2: Number of cruise missile trucks is 8. This is the first of two time-eating stages
3-A: Good news is that the timer stops when the alarm goes off until you regain control. the bad news is the alarm takes a few seconds and (AFAIK) is unavoidable. You'll use one of the 16 cruise missiles here, leaving 15 for 3-B.
3-B: 15 shots to work with, only 3 are required. You have to seriously lead your targets on this one or catch them right as they start turning.
4: First off:
**** Shark. Two hits are needed to kill Shark off, but only one is needed to finish this stage. If Shark is not killed now (a parachute hit counts as perfect, IIRC), he will appear in stage 5
5: The other time-eating stage, this time with virtually nothing to do even if you let Shark live in the previous stage. The number of shots you need is 3 minus the number of shots you used in the previous stage (assuming perfect accuracy). The last shot will go to the target's head. The other shot, if applicable, goes straight to our friend Shark.
