After much testing and meddling i finally managed to reach wave 7 in the NWS (but lost

) and since i couldn't find a nice topic discussing strategies on this mission i decided to start one so we can all share knowledge.
So, here are the things i found out :
1) Best ships for this mission are Cruiser and Science Vessels with a mix of both.
The minimum requirement being Commander + Lt Commander Engineering or Science BOFF slots.
You have read correctly, i do not recommend escorts because i feel they are a weight to the team in this mission, mainly for two reasons : first, it is very important to stay alive, if you die more than once you will most likely screw your team and escorts tend to go boom way to often; second but not the least, escorts simply do not have the adequate BOFF slots.
As you may have understood, cruisers will AOE spam to grab maximum agro, tank and if needed heal while science vessels will crowd control, heal and finally DPS when possible.
The DPS is *not* important and the most important things are, in this order :
keep the transport out of firing range from the ennemies, heal the transport, heal yourself.
2)
The waves are not timed, you have all your time, use it !!
No need to go all berserk, there is no timer so when you have only 1 ennemy left everyone but 1 person should stop attacking and start healing the transport.
The last team member should keep the last ship busy and away and wait for the transport to be fully healed before triggering next wave !
The ten seconds between waves are not enough to fully heal the transport so don't expect to survive next wave if your transport is not at 100%.
3) Devices like turrets and pets like Tal'Kyr/Saucer/Destroyer will not live long.
You can use them but be warned that they will die very very fast so time well their use because you will be left without for few minutes.
Concerning devices, everyone should have a Subspace Field Modulator for when tanking.
4) Imho the most important skills to have are :
- Tractor Beam Repulsors :
*very important*, i recommend 2 per science vessel and 1 per cruiser.
SPAM IT !! to keep the ennemies at bay away from the transport but also push away exploding ships, torpedoes, missiles, fighters ! And of course do not be dense and do not push ennemies toward the transport !
- Engineering Team :
*very important*, 1 per player minimum, to heal the transport.
- Hazard Emitters, to boost transport hull regen and/or cleanse it.
- Transfer Shield Strenght, to heal the transport.
- Extend Shields, same as above.
- Reverse Shield Polarity, for when you are going into the brunt of the fighting.
- Emergency Power to Shields, self heal.
- Beam Fire at Will, for cruisers to grab agro of nearby ships and shooting at mendatory plasma torps flying by.
- Torpedo Spread, same as above.
- Emergency Power to Weapons, extra DPS but remember it shares cooldown with Emergency Power to Shield who is more important.
5) Always keep the transport on focus (the pin button on the target) so you can quick select it without cursing at the melee or your team mates.
I strongly recommend you do not take the usual STF skills that are Gravity Well and Eject Warp Plasma because those skills will just pin down the ennemies and keep them inside their firing range to the transport instead of pushing them back.
Same for Tyken's Rift : it is a good skill but it will eat up crowd control and healing skills slots.
Remember everything i said is for waves 1 to 7, i do not know if it works or is adequate for next waves.
That is all i can think of right now, i will come back and edit this post when needed.
Please share your thought and your experience so we can finally beat this no win scenario !!
