Engineer skills and techniques - a starter

If I may add on to to wonko words, In OTHER, non-titan waves a high wall *if you dont have it for titan waves *+ ceiling defense sent is VERY effective in my opinion....

I survived 2 waves on 80 and Enjoeneer on >70 health in the last 2 waves ...*the def sent luckily neutralized the penetrating ice krall...and also any projectile coming towards the hole int he wall to shot out of...BUT..a back hole opened up in the base...
and I died..and my wall and sent died..and well..it all just went down hill for there...

....BUT that indicates that the def sents do help alot..

..more so in numbers....

Oooooh....Imagine 6 of them(Ceiling Def Sents)..

.....with a small wall youd be....untouchable...

...

Still....great build..
