HP vs Run Speed
So characters have way to much initial speed and HP, it takes so many bullets to kill someone and it makes the game feel slow. My sugestion would be to give the normal 2000 HP and 0% Run Speed and don't let full tank go over 300+ HP, full speed parts shouldn't give more than 8-9%. This will make it easier to balance weapon damage.
There is no need to have extra bullet armor and explosion armor, specially if the bazooka and grenade damage is balanced.
Characters
About the characters, there is no point in having so many characters. Just keep C.H.I.P, Knox, Naomi, Pandora and Kai, no one likes the others.
Upgrade system
I love the upgrading parts idea, it's nice that I get to choose what I want for parts I win in the capsule.
But i have a question about the weapons upgrade system. Is it only 1 level?
Weapons
The sniper was being used in close range fights too much, so the aditional zoom was a nice way to avoid that, still some snipers have insane zoom speed. For a low sensitivity player like me it's hard to move the scope so i sugest adding a setting so players can change their sensitivity while scoped.
Meeles make you go so fast it's hard to control and sometimes annoying. When i first played I didn't upgrade my meele and it felt pretty fast already (620 default run speed i think) then I upgraded it and it was too overpowered.
For the bazookas and the grenade launchers I feel like the power shouldn't go over 800-900.
Shop
Back in the days there wasn't much we could buy with RT in the shop, not everyone likes to risk their money on the capsule so it would be nice to have a shop that changes monthly/weekly, we would always have the normal MP items and ADV weapons but every month/week there was something different in the shop it's ok if the items repeat every once in a while. Also capsule items should never go to the shop and shop items shouldn't go to the capsule.
Im looking forward to the full game release. Have a good night!
