Yeah it was made in GM7 pro, sorry to disappoint you Mince Wobley! ;) Hope you might find it in you to try the demo anyway!
that looks very very awesome. a little too much like MGS maybe, but awesome indeed.
I've been told this before actually, but the whole point of the project when I first started working in 2007 was to immitate MGS down to every detail cuz I was a bit of a fanboy back then, so I don't feel that it's too much like MGS since with my original intention in mind it can't get too much like MGS;) We're trying to put some of our own twists to it though.
As for programming stealth in RM, sure it can be done, I did it at first but like you say it is very poor. The pathfinding gets sooo slow, and soliton radar can't be made the exact way it's done in MGS either, I found a workaround for that though but it was never a smoothly scrolling thing.
andyw: your portraits look pretty cool, what's up with the yellow thing in the upper right corner of the main character though?
