I tried to make Zaxxon from Sega in Construct2 . It uses the isometric-plugin from R0J0hound. It's more a 'prove of concept' then a 'work in progress'. It is only a third of the first level, because it is so much work to place the objects pixel correct.
Thanks @brushfe , @spongehammer, if you guys want, I can send you the link via PM, so you could try it yourself. But it's really short and has still some flaws. I won't post the link here because of the copyright from Sega.
