Recently I made a Campaign about Slaviks origins before the Tiberian Sun storyline through a GDI campaign as I just love the C&C universe and more specifically the tiberian sun story. I had fun making the Campaign so followed it up with a Nod Campaign where you the commander take your order directly from Anton Slavik as he takes his first command set roughly 5 years before Tiberian Sun where Nod has splintered and commanded solely through the Black Hand as they operate from the shadows, slowly building strength and researching new methods to gain power through tiberium. It's here where you begin your test of loyalty to Slavik.
Difficulty, harder than my GDI campaign much like the original game, definitely a test for some players, but if I can complete them then its not impossible. Check the description for some missions, as I admit I have been very cheeky in some of them, and you may need some hints.
Mission 1: From the Shadows
Slavik: I hope you're rep as a valued addition to the Brotherhood is well founded, as I've selected you to be apart of my leading commanders, serve me & the brotherhood well and the rewards will speak for themselves. Onto the matters at hand.
GDI are distributing Medical aid to civilians with tiberium related disease, The compounds in the medicine are of use to our science team. As I oversee construction of our Medical Colonies I need you to take a Commando unit into the area and obtain these Medical Vials, there should be 3 in total.
Images show a Northern Village with 1 Vial, another in the Eastern Village and the 3rd still unused, likely still in the Armored Personnel Carrier transporting them, and we see the APC is in the GDI Outpost on the shoreline.
Be VERY aware, destruction of GDI Main infrastructure will cause a drastic response, avoid this at all costs, watch towers should be acceptable. Finally, if you access the GDI outpost from the shore, be aware of the GDI patrol Boat.
