Ever Seen This One Before..

DeadlyFreeze

<div class="IPBDescription">wth glitch</div> First time I've seen this happen...(the picture is kinda dark but if you cant tell its a alien resoucre tower stuck in the ground, it was still collecting resources but we couldnt kill the damm thing)

Inexorable

I've seen it before (only once, and at that same resource node). I think it got killed by a nearby siege cannon though, so I can't confirm any sort of invulnerability it may have had.

BattleTech

I've only seen that happen with Marine Resource Towers.. It sunk underground and was just a big "glitched" model where the gas node was.. freaky.
