Place and activate wormhole digger in order to transport Sahelanthropus
There is a nearby Wormhole Transporter if you had activated the same you can quickly reach that place. If not then once again you have to travel a long place. So best to activate it first, and later place the digger near to the weapon. Set up fences around the digger. Because once you activate it a lot of enemies will be drawn towards it. So at the base fill up your inventories. You will need a lot of defensive units.
Defend wormhole digger unit transport is completed:
Try adding some fences around the digger to slow down the enemies once they attack. You can cover it nicely and you will have to defend it for really long time. That is 15:29 minutes. The digger is kept in between the mountains near the base, you can also place the fences to block the passage. Look at the minimap for enemies location. You can plan your attacks. Either you stay back or you reach near the red circles to kill the Wanderer’s. If you plan to stay back you will have to face them in groups. You will have to defend the digger till the clock is ticking. It depends on how well you can use the weapons that will tell you to kill more than one enemies. Using the Bomber against them is the best option. Use fire arrows on Bomber once you see a lot of Wanderer’s around, it will kill them in one blast. As the time reaches around 10:00 you will have to face the Trackers also.
More and more enemies will try to appear in the group. Some will jump from the mountains around. Try replacing your fallen fences. Using fire against a horde of enemies is an ideal way to kill more than one. As usual, they will get accumulated between the rocks that the time you can attack with fire arrows and kill more than one. On the right end of Digger near the wooden structure, you can find a Mortar that also you can use in killing more than one enemies. It is best to destroy those who are shooting you. After a long fight, there will be cutscene that will show the weapon being extracted to the base. This completes the chapter. Return to the base.
