Honestly, the dime a dozen free games have never been popular for multiboxing around here. As I've stated numerous times, HotKeyNet isn't written for any specific game. I've written or done troubleshooting for tons of HKN scripts for all sorts of games and they all use the same basic scripts with minor variation to account for game-specific mechanics and quirks.

If you want to use HotKeyNet, you're going to want to get familiar with how it works. Start with the HotKeyNet Newbie Guide - I go through a starter script step by step explaining exactly what each thing does and how to make changes. You will also want to spend some time on the HotKeyNet site, especially the forums and the Commands reference. While the forums themselves are closed, all the posts are still there for reference. You might even find something on one of the games you mention.

Assuming these games even allow multiboxing, which they very well may not, it shouldn't be too hard to set up a script based off already existing scripts. I can help you troubleshoot, but you'll need to do the work as I don't really have any interest in researching, downloading and setting up games I have no intention of playing. To troubleshoot you need to include the script you're using and the messages that HotKeyNet is putting out.

If you're not up for that kind of work, I'd suggest seeing if ISBoxer supports games like those.
