It’s Crossbows and Catapults, but in the future, and with shape-changing robots. Lakeside Games made both sets. Crossbows came out in 1983, a pretty brilliant concept that successfully cashed in on the D&D action. Immortals of Change came out in 1985, a cool-looking bomb that badly wanted to sop up some Transformers spillover.
Why did it tank? The name is awful, first of all. What the hell does it mean? Second, the game was overly complicated and didn’t work the way it was supposed to (the glider in particular, as I recall). Third, the concept made no sense the second time around.
The cool thing about Crossbows was that armies actually used giant crossbows and catapults in the Dark Ages. Why would immortal “battle machines” from the future hurl rocks at one another? Transformable robots have lasers and stuff. Everybody knows that.
The commercial below is very low quality, but it’s the only one I can find. You can tell they’re really trying to give the game an edgy feel. The volcanic landscape, the red lights, the smoke—it looks great.

Holy–I had NO IDEA there was a scifi version of Crossbows and Catapults! C&C was one of my favorite games as a kid. If I’d known Immortals had existed I’d have begged my parents for the entire set. Looks awesome!!!
I LOVED me some Crossbows & Catapults. Probably the best thing about the game was they just gave you toys and a set of suggested rules. It was as complicated as you wanted it to be. My friend and I would play for hours.
I just found this page by accident, can’t even recall how I got here haha but as an 80s kid as I was curious about this line that I never heard of. I bought the battle set on ebay, for rather cheap and the concept is cool on itself but yeah the whole space angle is weird and the name is weirder.
