GoW and Blockland arent in the same league. those who say GoW sucks, probably just suck at it.
anyways, back on topic. why would you want that in Blockland? i mena the idea is ok, but to see a non-lego weapon wudnt be as good as a lego one that does the same. it would probbaly be doable. complicated, but doable. and probably laggy.
g'luck tho.
