Build A "Siege Breaker" And Push Your Way Through The Forest To The Greed Cave.
This Is Story Related, You Must Go In Here Anyway To Find The Level Exit Vehicle.
Be Careful! Upon First Approach, Most Greed Portals Seem To Spawn Slug Beasts To Halt Your Advance.
Slug Beasts
- You Can Backpedal Your Siege Breaker Away From Them
- Keep Them In Range Of Your Backpedaling Archers!
- Killing Them, Then Pushing The Siegebreaker Back Up To The Portal Seems To Not Spawn Another For A While. (Spawns Might Be Based On Total Portal Health, Not Sure Yet ;D)
Good Luck!
