Atomic Rocket Games can be reached for most purposes at the handy e-mail address of arg1 (at) atomicrocketgames (dot) com. Pardon the lack of a clickable link, but we're trying to cut down on the spam we receive. Drop us a line and we'll get right back to you!
Please be aware that we cannot answer questions like "Why did R. Talsorian Games put (x) in (y) book?" or "When is (x) going to be released by R. Talsorian Games?" or "What size shoes does Giant Robo wear?" because we just can't answer those things.
However, if it's related to Mekton Errata, or the Mekton Mini Campaigns, or anything else we produce, we can certainly help you with that!
