We weren't sure exactly how to link to it, so we used the "Send To A Friend" option and sent it to ourselves.
The video's great. We don't want to give anything away, but please note the following:
There is some mild language used.
There are some install requirements to view it (Java applet)
The trailer also "lightly" touches on the system requirements for Crysis.
You can view the trailer at www.ReadyForCrysis.com.
