I too wish you the best of luck, because I agree with what you've said here.
A thought I had recently; I wonder if there is a way to use Legendary Encounter: Alien Deck building game cards to create variety in AvP:Hunt Begins. Afterall there are already full barracks and alien hive cards available. It that's a seperate idea/thread.
Here's some ideas for you:
"They mostly come a night" - all Aliens this turn operate with hidden modifiers.
"Let's build a camp fire, sing some songs" - aliens in hidden lose their modifiers this turn.
"How do I get out of this chicken Sh!t outfit?" - marines movement is a run (2) instead of (1).
"What are we supposed to use? Harsh language?" - marines cannot use pulse rifles this turn. Flame and shotgun weapons only. Roll 1-10 on smartgunner to see if he remembered secret ammo.
"Flame units only" - it's what it says. Other units get additional move to create retreat effect.
"What do you mean they cut the power?" - marines reset back to tokens this turn even in LOS.
"Short controlled bursts" - marines get ROA 2 if targets are one tile away.
