perk-a-cola changes over the years

[yoyobobguy2]

i was curious about the changes to perk-a-colas over there years.

 

i am making my own perk-a-colas from some online tutorials, and i wanted to know about how the perks, and their logos, have changed over the years. obviously as the graphical improvements were made to the game, the bottles and logos were updated slightly, but there was some obvious changes over the years (most notably double tab -> double tab II and sleight  of hand -> speed cola).

 

is there any other changes that have been made to any of the perks throughout the games? i have seen logos of 'quick revive soda' and just 'revive soda', but i cant seem to find any in-game images of "quick revive soda" just "revive soda". does anyone have a link to the logos, or the textures from the game files. i am also curious if there was any material changes to the way the perks work. as i understand double tab 2.0 use to consume your ammo for each extra head shot, but now it just doubles the bullet fired.

If you are still wondering, the only real differences with the Perk-a-Colas has been the logos in the corner of your screen. Other than minor graphical upgrades as games progress, the bottles and logos have stayed relatively the same.

Speed Cola was never called Sleight of Hand, people just used to call it Sleight of Hand because it did the same thing as the multiplayer perk of the same name. Same way people used to call Juggernog "Juggernaut".
