Hi , I was thinking that you should get medals for the amount of npcs that you kill :
100k
250k
500k
1 mil

I think 1 of the rewards should be a npc unlockably ship skin : this means that your ship can get the design of any standard npc ship that you wish .
Another reward would be the ability to change the colours of the npc design .
The next reward would be the ability to change your ship to look like any npc boss that you wish
The next reward could be to alter the colour of the npc boss skin thats on your ship .

What do you guys think ?

Loving the idea, I can always use some new medals. but i dont think they will all get rewards, because if you look at the system as it is now, less than 1/4 of the medals have rewards other than medal points.
But, you might get one or two rewards out of it, for example the unlockable ship skin for 100k, then for example, a new ally for the 1M kills.

But, can we make this one slightly different than the regular ones? I mean, no offense to Dan or anything, but the "max at 100, bonus at 30, 60 and 100" thing is getting boring and predictable.
Also, since it would be a reward based on NPC's, it should help with NPC's.

So, with that in mind, the ally would look something like this:
Alterian, Neutronic Titan.
2% increase in Alterian, Neutronic Titans stats, while upkeep increases by 4% per rank. Max rank 200.
Rank requirement: Each rank requires you to kill 1500 standard NPC's. (Bosses, Elites and Mission based NPC's do not count)
Starts with:
Upkeep: 200M credits/day.
Attack: + 90. (before Bonus)
defense: + 120. (before Bonus)
With ranks:
Rank 40 Unlocks:
Hull: + 240 (before bonus)
Rank 80 Unlocks:
Shield : + 160 (before bonus)
Rank 120 Unlocks:
Energy: + 60 (before bonus)
Rank 160 Unlocks:
NPC attack: + 6% (permanent while ally is installed, no rank bonus.)
Rank 200 Unlocks:
Ability: Call to aid. (The Alterian, Neutronic Titan lures in an NPC elite, by sending out a distress beacon. Summons 1 random Elite NPC to your battletab. 40 hour cooldown) (only Elites within your rank-range of course)

Maxed out, it would look like this:
NPC kills to max ally rank: 298,500.
Attack: + 448.
Defense: + 597.
Hull: + 1195.
Shield: + 796.
Energy: + 298.
NPC attack: +6%.
Ability to summon 1 random NPC elite, 40 hour cooldown.
Upkeep: +1.792 B/day.

Any thoughts on this? Keep in mind, all the details can be changed to make it more or less powerful, as needed.
