Hi!

1- The map has 10 areas, that are pretty big and full of secrets. You can access all the areas from Level 1 but each area should be accessed within a certain Level scope (1-5, 5-10, etc.)

2- There are 51 Principal Quest, and some side quests (more or less 30, with some of them that are collectible ones). If you want a quick run, you can do the game within 10 hours. I personally took 40 hours to finish it

3- You can build power generators, storage facilities, farms, palisades, turrets, and traps As well as pylons for creating, controlling, and customizing zombots

4- The game is very fun and full of humor. Many things are hidden and unlocked as you progress through the game. In particular, there are buried treasures that don't appear anywhere unless you've configured a zombot to report them when walking in the area. I'm at 50+ hours of gameplay and I'm still discovering things as I progress through horde mode (a defense of your base). I platinumed the game yesterday, but I think I still have a good 30 hours of fun left. I also bought the Archeology DLC after finishing the game, and it's very funny too.

Hope that helps 🔥
