This was the very first issue from MLJ, later known as Archie Comics. It was published by them, but likely not produced in-house; it contains some characters that had already been published by Centaur that Centaur apparently didn't own. In both cases, the producing company was likely Chesler.
What do we get here for hi-tech? We have some kind of rocket ships, an invisibility field generator, and an "ultra-scope." I can't even figure out what the ultra-scope is supposed to be doing. Is it detecting the invisibility field? Is it allowing them to see the space freighter before it disappears?
It's also telling that the first two items are not only already statted for Hideouts & Hoodlums, but have been already seen in stories set in the 1930s. So the future is only hi-tech in its trappings.
Another example of 1930s tech -- an electric eye triggers a recorded message that serves as an alarm. You'd think a louder whistle or siren would work better, but okay...
Another handheld paralysis gun -- just like we just recently saw getting used against Shock Gibson back in the "present."
The tactic about using a blast gun to propel himself into the air in low gravity is a clever one. This is also the first time we've seen this referred to as a rocket blast gun. I don't know how much damage to assign to a rocket blast gun -- maybe 3-18? It doesn't look that impressive, despite the cool name.
It's always a good idea for your boss villain to have an escape route handy.
