Forgot what we call them officially, but I'll call them "uber weapons" ... the "uber weapon" stickers.... I managed to buy all and add to sticker album, didn't get ach. can someone help me? what do I need to do to ge this achievement. Thanks

The achievement is called Not-Quite-As-Legendary Champion.

Did you go to the achievement page, items, stickers and click the "show required items" button to activate it? If no, go do that. If yes, were all items actually green? If yes, wait 1 hour. If you still don't have the achievement, submit a ticket explaining what you've done.

Also, its not just the basic stickers from the millionaire center. You need all those, but also need to combine all the basic stickers at Genetech to get the combined weapon stickers too.

d'oh! I forgot about the gentech combos! guess I'll be buying those stickers.. or are they cheaper to combine to get them?

Probably cheaper to make them. Just checked with one example - Acidtongue, costs 5M in user shop, vs 2 million to buy both stickers and go make the acidtongue.

If you're also working on the buying from the million center achievements, that also favours making them yourself. I can't remember how many of each sticker you need to buy, it was a long time ago that I did it, but it should quickly up your total.

you've been a great help. thanks so much. I'll work on making the combos for the rest of the stickers...
