Mission 4: C2W

- If yo[Subsistence]'ve been keeping up with collecting materials, you should now be able to develop some C4. This isn't required to complete the mission, but for one objective it is mandatory. Go to your iDroid and head to the Mother Base tab, then to Development.

- Note: If you want to complete an optional objective (initially hidden), initiate the mission, then travel to Da Wialo Village to extract two prisoners. Interrogate guards or simply search the smaller buildings on the southwest of the Village (one next to the main road, the other to the west from there) to find the two prisoners; drag them outside to Fulton extract them. Head back to the Eastern Communications Post via the south road.

- Your goal is to destroy equipment at the Eastern Communications Post, which can either be three satellite dishes or the radio transmitter (inside one of the buildings), or both, if you want to complete all mission objectives.

- Approach the post from the east and look for a mountain trail to the west side of the road (before the main road curves off to the west/to the base). Be careful of loose patrols and wolves. This trail leads you to the hidden rough diamonds from one of the (initially hidden) optional mission objectives. The Rough Diamonds are found in a rock wall.

- At the end of the trail, recon the enemy outpost entirely, and mark the three satellite dishes (an objective). After this, place C4 at them while carefully making your way through the base, neutralizing any enemies you deem necessary.

- If you also want to destroy the radio transmitter, head inside the building in the center of the base and shoot it with a regular weapon. This will most likely attract the attention of guards, unless you've dispatched them.

- [Subsistence]-Rank Tips: Speed and Stealth are as usual most vital for securing the highest mission rank. An easy way to achieve this is to plant some C4 on the radio transmitter; sneak in, plant it, sneak out, detonate the explosive and exfiltrate the hot zone.

- General Tip: From now on forward, you should focus on developing Mother Base platforms whenever they become available. Inbetween missions, always reassign your staff by going to the Staff Management menu and pressing the right analog stick, so they're on their best possible positions. Under the Base Management menu, focus on developing the R&D Platform, Base Development Platform, Support Platform and Intel Platform.
