I've read there were plans for an ALIENS cartoon at some point, presumabely based on the early 90s action figure line. However that never materialized. (There was some controversy back then about 'toons being based on scary or R-rated movies, like the Rambo cartoon; the same thing sunk the Jurassic Park cartoon as well).
There's some decent Alien comics from Dark Horse. The early ones were made between Aliens and Alien3 and are the continuing adventures of Newt, Hicks, and later Ripley when the Aliens manage to invade Earth. However, later editions (and the novels) re-edit these to better fit within Alien3's continuity by changing Newt and Hick's names and making Ripley an android.
The Aliens/Predator stuff also got it's start in the comics as well before the crossover films.
