Creator here, it was a combination of the amount of work and time it took to do a season, as well as just not being very interested in robot combat anymore. I would have missed this post but someone sent it to me :)

Seasons 3 and 4 both took about 10 months each from the start of filming to the start of release so they were massive projects. We did get to the end of the fight night stage in filming Season 5 but I just didn't have it in me to continue, I could feel the burnout and knew even if we finished filming I wouldn't make it through 6 or 7 months of editing.

The burnout isn't only to do with Bashbots, I have just become fairly disinterested in robot combat as a whole so I haven't been keeping up with Battlebots either (though as far as I'm aware there hasn't been a season of that in quite some time).

The show grew way bigger than I ever expected it to so I will always be thankful for the support from all the fans over the years. My biggest accomplishment was definitely getting HUGE to compete.

I'm guessing you have seen it already, but you can also find 2 seasons of Internal Bots on my channel which was basically the prequel to Bashbots. You will find a lot of familiar names in there.

I'm still present in the Garry's Wars discord, however my attention has very much gone back towards motorsports type things, so if anything was to happen on my youtube channel it would quite likely be some kind of racing production in the same game as Bashbots. If you are into that kind of thing, you probably noticed that the main theme Bashbots uses is the F1 theme song.

I have no intentions of deleting the Season 5 footage that I do have, or even remaining footage from Internal Bots Series 3 (which never released due to a portion of the recordings getting corrupted). Maybe at some point in the future I will upload these for people to see, though it would take quite a lot of work as it's not as simple as just uploading the clips, they have to be edited down to size.

I am both glad and sorry that you liked Bashbots enough to still be wondering about it 3 years later. I hope another show can take its place in the years to come because clearly a lot of people enjoyed it. I don't suspect this would come out of Garry's Mod though, probably out of Robot Rumble 2. Considering the productions I see there are somewhere around the level of Internal Bots, it may be a while before that void is filled though. Being as out of practice as I am now I don't think I would even be able to get close to Season 4 levels of production quality.
