[PS4] Super Robot Wars OG: The Moon Dwellers - Only One Crash Trophy

First of all - I didn't plan to get the trophy this way - there are lots of ways to do it easier. When I've done some preparations I just thought that my Neo Granzon is able to deal more that 50K damage with a single Degenerative Cannon even to tanks like Zui Gadin, so why shouldn't I just push the record button?
Preparations that haven't been recorded. First, it's Special Mode, so any unit has 15 upgrade ranks instead of 10 (and of course, all 4 units are maxed up). Then I wasted SR point at stage 38 to be able to collect as much money as I want and to max up Shu's range ability (walk through the map with Granzon using Advance or Chain Attack, kill as much enemies as you can with his Map attack using Bless for money and Cheer for exp, upgrade to Neo Granzon, continue killing until you used all ammo, use Cartridge, continue until you used all ammo, then have your other units kill Super Soul Saber with Map attacks to fail the mission and save gained exp, PP and money) long before that. In this mission I had maxed everyone's will (except Touya due to his Ace bonus, but he still has more then anybody and definetely much more then required to Maximum Break). I also had Leona to attack Zui Gadin with Mind Blast using Smite to break his buffs, used Advance on her and had her attack with Armor Breaker using Smite to debuff him with Armor Down L3. Before the attack I had Excellen used Exaust 10 times on Gu-Landon (had to restore her SP many times with Aspiration and SP Drink) to lower his will down to 50, used Valor on Shu and Touya and used Militate on Katina and Kohta (using Valor has no effect on the second pair in Maximum Break, while Militate does).
This video is how to get the trophy the hard way. A much easier way is to max up Alteisen Riese (Kyosuke), Rein Weissritter (Excellen), Dygenguar, Aussenseiter, SRX, R-Gun (Mai is better then Viletta for max damage), Wildwurger (Arado) and Wildfalken (Seolla), max up pilot's will, put Armor Down on any weak grunt enemy in stage 46 and use Maximum Break on him using Rampage Ghost, Tornado Blade, HTB Cannon and Twin Bird Strike with Valor's and Militate.
