Someone mentioned unfriendly aliens, but what if we become the "unfriendly aliens"? Seeing as we fought many wars throughout history, that's bound to happen sometime in the future.
EHMAHGERD I HAVE BEEN QUOTED BY THE WAR MASTER *ahem* 61. Fighting back is pointless, my friend. There's nowhere to run. You belong to me. Now, onto more pleasant things. Try to negative it again, and I'll destroy your pitiful army. TTFN.
I never really used the LV-N, as I preferred the Skipper (Oh god that engine is PERFECT) and other engines. Though now you can use jet fuel with the LV-N, so crafts using it should be somewhat lighter now, and carry more fuel.
