Yeah they are pointless platforming "missions". Basically, it's a first person experience where you walk through some pretty cool levels that sometimes correspond with what Desmond is talking about. All the while, you'll be creating either cubes or ramps to platform through obstacles. I loved the actual level design but... If you want a basic idea of what you'll be hearing, you'll hear about Desmond's childhood growing up in a "cult", escaping said cult, his life in the city, and finally being abducted by Astergo.
