Chicken Invaders Chicken Entrance and Movement

Hey guys,
I'm trying to create a game similar to Chicken Invaders.
I need some help figuring out what will be the best way to approach the entrance and movement of the chickens.
Any suggestions?

Here is a reference video of the game.

Thanks.

 

Did you google for "unity make space invaders" ? It returns quite a few complete tutorials. There are also plenty of generic shoot-em-up video tutorials that can help you get ideas for other types of alien motion, or chicken motion for that matter.

 

Hey,
Thanks for the replay, I've done some searching with google (I never create a thread before doing a complete search) and i did see how they manage the movement in "space invaders" tutorials; which btw doesn't seem generic at all.
My main problem is how to get them to enter from the sides in a generic way and then when they reach their "goal spot" the "selected type of movement" is actually starting.
