This original 1000g was about 1 hour.
THEN IT WAS UPDATED to be harder. (2-3 Hours)
Most recently, me and Xitilon have been doing an Experiment to see if Achievements effect sales.
SO IT WAS UPDATED AGAIN! **Now it is a 5-10 Minute Completion**
For this Achievement, we can Play ANY MODE. Simply walk to the right of spawn point and REPAIR the machine. Next purchase one of the Explosion attacks.
*Previously we were required to use the weapon. Now you just need to buy it
