Wait, hold up I see that my reason has been invalidated, so I'll make a more elaborate one.
Again. Mando is a highly skilled fighter, being able to use his environment to his advantage, as he quickly knew what to do when faced with several opponents on a ship, even ones that they are physically stronger than. He manipulated the ship to seperate the opponents from each other, and picked them off one by one in the dark. The Player doesn't have that kind of strategy in terms of combat practices.
Second of all,
Storm Hammers don't block flash attacks of any sort, its simply a melee weapon that can severly damage other players while doing a bit of splash range damage around it. It cannot block flash charges, and after all, it's a flash. It's not supposed to be blocked anyway, it's mainly used to blind the opponent.
Bee Swarm Spell doesn't fire as fast and frequently as whistling bird missiles. Whistling birds fire all at once, while bee swarm spell fires one at a time. This may block a few of the missiles, but most of them are going to hit their target.
Sticky mines actually have to be
stepped on to be detonated. In Pixel Gun 3D, they can be fired on a careless player, who happens to run directly in front of them, Mando is no careless foe. They're also not the same as sticky bombs, they can be timely activated. So, no argument is really there unless I'm mistaken.
The Sniper Mask can avoid a headshot, but it does come with a catch. There is a
10% - 25% chance of it doing so, and I believe it has to be done while holding another sniper weapon. This chance is rather low, and this can lower the odds for that happening. Plus, I'm sure that if you can't attack the head, there are other parts of the body to fire at.
The Void Ray Rifle (especially due to the
Speed of Light feats) could be a problem, but it has its bugs. It's not very accurate at far range (I said, close earlier my mistake) due to the lack of scope and it can run out of ammo quickly, so it cannot fire forever. This weapon like most weapons would also be useless if cover fire is also used as well. It also doesn't disable permanently, it has a temporarily disable. Plus, the Void Ray Rifle can only be used to
"disable gadget use beforehand, not disable gadgets altogether".
All of these points, plus the fact that
MANDO IS ALREADY A SKILLED COMBATANT. He could use various strategies as well, like he could use the jetpack, fire the flash charges, and then attack while blinded, or use this stealth mastery to sneak up behind him and then attack. The Player isn't generally a strategist, when it comes to combat. The only advantage that the player really has is that he has better, more powerful gadgets than Mando by sure, and that resurrection which would almost make this battle unbalanced and unfair. But, I don't see resurrection gadgets listed as Standard Equipment nor do I see some of the other weapons listed, but who knows.
Not entirely sure how force-fields work I haven't played that game in years, but I believe they only prevent you from being spawn-killed. Let me know if I am mistaken on that. But, such weapons would make him OP (like Resurrection) and I don't see that listed on his Standard Equipment.
I also don't know all of the code weapons, and other weapons that he has, so let me know if there is something that I should be opened to.
