Honestly project elite is the best alien blaster game if that’s what your looking for. And even Aliens: Another Glorious Day in the Corp works better with an awesome endurance deck mechanic. No need to go second hand market either if you don’t want to.
Legendary Encounters: An Alien Deck Building Game is a different kind of beast but it’s really cool too. The way the enemy reveal works is very thematic and the various Objectives make a great use of the Legendary enemy-river system.
Never had a chance to play this but I researched it a bunch and I almost picked it up a couple times. Looks like a fun dice-chucking romp. It uses the tile based map reveal that Sub Terra and now Clank Catacombs has too. Sadly it seems to be out of print now and according to a BGG comment the publisher may have lost the license for this one too.
Oh wow that sux! I really love the alien theme, always a bit weary about coop games to be honest but it sounded interesting
