I bought a gold bazooka once to get the achievement, but ever since using it, and running out, every post battle ad from that point on wants me to buy one.

10~ battles later, with closing the browser between some of them, and it still pops up.

I just ended up buying it so it would go away.. (please deposit 4 cash plus interest in to my bank) but now the generic "Victory, stock up.." ad is there, and wont go away.

Pretty sure in the past when I finished games there wasnt always an ad.

Hey Sephiroth, you'll be pleased to know that we've toned down these screens. This is something that is still in the very early stages of production and we'll be building these up in later version. Thanks for playing!

Quick update... There are still more changes due to be done in these post-battle ammo adverts. Thanks for your patience! :)
