The task of catching ’em all in Pokemon Go will soon get a little tougher. The smartphone game’s developers at Niantic announced the game’s biggest expansion yet, coming “this week,” which will add a grand total of “more than 80” creatures introduced in the series’ Game Boy Color games Pokemon Gold and Pokemon Silver. When the update goes live, those characters will be seen wandering around your real world, as opposed to requiring a more obtuse method of discovery (i.e., hatching eggs).

But the bigger news may be the other tweaks coming to the game alongside so many ‘Mon—and how these all seem designed to open wallets to more of the game’s microtransactions.
