When we started work on Commandos 2, we threw away everything from Commandos 1, and started from scratch. 15 years down the road, all the coders still agree that was the best decision ever.
Man, I loved Commandos 1 back in the day. I recently got a bit nostalgic and bought the whole series on Steam, and they are still great games! But MAN are the controls opaque. Thinking back, I think the game came with a little cardboard sheet with all the controls on it, which would have been easier to deal with.
Fantastic game though, thanks :)
