theres a achievement/trophy for combining two vs's. anyone know how to do this?

To OP:

Start on EP4 CH3 (4-3). You have to make sure you're inside one of the two VS that are on the map, the ones with the optical camo, before it ends. When you go to the next Area, you should still be inside the VS. Exit it and leave it where it is. Go on until you reach the second lightning post switch, the one before the second spider. Go into the cave at the left and you will find a tank. You need two people for this.

Make sure both VS are active and stand near eachother. Each player should press these:

L3 and R3 (Or your analog sticks on the X360 pad)

Then move them "outwards".

Move L3 to the LEFT and R3 to the RIGHT while holding them. Then you'll see the Merge button, and it's smooth sailing.

I hate how not that many people know how to do this, if I wasn't on Unity, I would not have ever known this existed unless I randomly checked my VS manual while driving a Cakti.

thank you so much everyone. its been bothering me for ages. <3 u all

I still think the Triseed and hardballer should combine into a L-P-9999 I mean they do look like they have the part to do it, and what about the Hardballer armor from the first one I forget it name it when the boss had his father hardballer.
