The original Duke and 3 expansions available to download from Steam for a mere £1.74. It might be old and a little dated but it's still a better game than that recent version.
Emp you legend. I am getting this now! I was so gutted to have missed it on the humble bundle deal the other week, but this more than makes up for it. :D
I used to spend hours making multiplayer levels using Dukes Build engine.
Well you can play it on iPhone, as it now app.
I picked this up bundled with Shadow Warrior for about £3. Well worth it in my opinion, especially with all the expansion packs for Duke. :D
