EDF 6 / Earth Defense Force 6 - Things that suck

Sadly this list will be long 😞

EDF 4.1 - Missions Data - Info, tips and details

As it's easier to me I'll use reverse order of missions.

Mission 38 - High Density

A photo of the map of the second phase so that you can see the location of the tunnel exits spitting silver spiders and gold ants. To be clear, the silver spiders one is visible with 2 over it in the middle left, the first in the middle of the road is one of the golden ants tunnels, and the one on the far right just left of the rightmost crane and below the radar in the pic is the second golden ants tunnel. 

The tunnel to the right of the central goldies one, which is almost hidden by a warehouse, is a bogus tunnel, and no enemies spawn from it.

It is possible to destroy tunnels as they're spawning without enemies aggroing. Solo, you can only go for one. Very useful at the start of each wave, especially in the 2nd where you can destroy either the central goldies (easy) or the silvers (harder), and you must use a powerful and precise weapon (Monster-S, Stringer J3 / J7).
