That's pretty cool to see the battlescape running on the simple ZX Spectrum hardware .. sounds like it needs at least a 128k Spectrum, or the further expanded Russian Pentagon/Scorpion machines to work on. (according to
World of Spectrum) But impressive nonetheless. I'd try it if the text weren't all in Russian.
I was even more surprised to see that there were multiple levels and environment destruction. A shame there were no line-of sight restrictions, but I guess that's a little much to ask. ..not sure the igloo to everything-else ratio in the ice levels is realistic.
