I'd be surprised if it's anywhere near that exotic. It'll just be a webpage with a list of games you can pick, input a number of "installs" to fake, and it'll fire the requests off with Javascript. Or maybe a browser extension if they feel the need to distribute the requests. Half the gamers will install it at some point when their favorite absurdly over-hyped game flops.

There's not much need to run an optimized and complicated tool like JMeter when each request costs the other side $0.20. I wouldn't be surprised if a browser extension could get out something in the ballpark of 100 requests/second.
