On Base tips

[UBER GOOBER]

I had trouble with this achievement for Vindicators Part II but I was able to unlock it with this strategy. After getting used to the horrible controls of the tank on level 1 I stocked up on the stars & fuel while also blowing up the tanks and after passing it I bought the shields which cost 4 stars. For the next 2 levels I moved up avoiding turret & tank fire until I got to the base then I blew up the tanks & got into the base. While inside you have 10 seconds to get into one of the doors after you do that achievement is unlocked.
