Just a random bit of lore, but apparently this won't be the first ship named "Endeavour" in the Aliens universe. I'm finally reading through the Alien RPG's Colonial Marines Operations Manual, and I came across this little factoid in the universe timeline section:
Quote from: Alien RPG"2162 - The UA, 3WE, and ICSC form the Allied Frontier Force (AFF). The USCSS Endeavor is destroyed by the UPP. The Tientsin Campaign begins. "
Though here it's described as a "commercial survey ship" rather than a warship like in the game. Still, with all the deep cut lore references it looks like this is going to have, it'll be interesting to see if any of the NPC marines make reference to its namesake.
