add Defend the Bombs mission type

[Leo.doodling]

I think for added variety DE could use the Defend the Bombs mission from the Natah storyline as a new map type. I was playing it for the first time last night and felt like a nice remix of the normal defense mission. (And not sure if these mission types are around later in the game, I'm still working my way through the story).

Personally the defense missions I usually find to be the least entertaining. So at least with the defend the bombs mission it had you changing locations for each wave. For a mission type of this kind they could even add a randomize to which bomb would be next to defend. 

And for 'story' reasons it could be bombing a Grineer mining facility or destroying a Corpus robot factory.

This mission of defense is available on Uranus defense already.

well you have the mobile defense which is I think better because you are not stuck in just small part of the map and then you have defense missions where you defend some NPC thats walking around regular defense map, and thats annoying
