first one looks like pack a punch and it makes pack a punch cheaper
from 5000 to 1000 but this is only 30 seconds or how long the power up lasts
other one is $ icon it makes mistery/random box cheaper
from 950 to 100 (I think its 950)
BUT I'm not sure does the $ makes other guns cheaper... I think it only affects the mistery/random box
There is also an death machine power up...
u have that machine gun for like 1 minute or 30 seconds
