Does Resistance have a demo? Will R2?
Yeah. I wouldn't bother with it though, and I say this as someone who liked Resistance quite a bit. It's fun enough, but it really hasn't held up well. The SP has some very cool moments, but it felt like the company was sort of holding back on the craziness, something that they don't seem to be doing this time around.
That said, I still don't think Insomniac has received quiter enough credit for the online aspect of Resistance, considering when it was launched and on what system it launched on. Great online performance, awesome clan functions and stat tracking, it was really quite impressive. I don't think I could go back to Resistance online after playing COD4, but it was great for its time.
edit: Never mind, I thought you hadn't played it. Yeah, R2 will have a demo, hopefully both SP (or from the cooperative campaign) and MP.
