Crafters of S.H.I.E.L.D. is a mod mixup based on having fun with friends.
The pack itself is focused on tech and transport with a glimpse of magic involved. It's good for experienced players who are looking for a SMP friendly pack.
Multiplayer experience is mostly affected by the people you play with. The pack is better suited for being at peace with your neighbors, but you can also totally destroy everyone you see (not recommended, they'll blast back)
Each part (Tech, Magic, Storage, Farming, Transport) is split in different paths focused on each of the mods separately. You can choose one and stick to it or you can do them all at once, your choice.
