That was pretty rad. Nice animation and fairly unique. I mean the story itself seems a bit derivative and similar to countless other madness plots, but the actual action is executed with a somewhat uncommon stylishness. It shows in the execution kills, which are diverse and carried out with a variety of weapons. They really have a lot of momentum sometimes, but they're also a bit slow. I also quite enjoyed the shootouts though they are sometimes dragged down by the enemies' occasionally abysmal reaction times and the very lackluster amount of suppressing fire they lay down. It's especially disappointing with those elite armored guys. Most of the enemies at least try, though, and they are pretty smart and do manage to hurt the MC, which is, I feel, a great touch as it shows that he's not invulnerable while also getting him to show his abilities, and you did it very well.
Not a perfect madness animation, but certainly a fresh one with a lot of effort and skill behind it. Keep it up! Also, have you really not animated madness in 10 years? Wow.
