A while back, I converted the Atlas Dreadnought that was introduced in the awesome TOS themed Agents of Yesterday expansion in Star Trek Online for the FASA system. I was holding off from doing a Star Trek Adventures spaceframe until I had the right artwork for that style and JAFisher44 came through yet again! I've used his 3d models (link here) in the past for my Pioneer and Derf STA writeups and he didn't disappoint with his take on the Atlas either.
I deviated a little bit from the STO version of the ship as I didn't want to stray too close to either my recent Pioneer writeup or my original Hood Class dreadnought in terms of stats and talents. If you want something that replicates the official console that comes with the ship on STO, just replace the improved shields talent with improved power systems instead (or just take it as one of your optional ones as it's on my recommended list as well). As with all my fan rules, feel free to comment below. The full size image is available if you right click/open in new window on the pic or just download the pdf version linked below.
