To get through the main campaign it takes about 40-50 missions (about 4-5 hours) but the levels are generated procedurally so it just carries on generating more missions forever. We're going to add more content through updates so that might increase further depending on what people want.
Wow this looks amazing. This reminds me a lot of the old Modern Warfare. Really can't wait for this one! @AndyShortRound, do you guys have a Twitter account?

Arrrgh, would absolutely love this if it was a twin stick shooter. Wouldnt mind trying out a lite version or something as i'm not personally keen on the control method (Sure some people like it). Does look great but wish it was a twin stick game, going to wait for the reviews
