Here's the plan.
The rocket ship will be brought because without it you wouldn't be able to get there. Once you take the ship, you'll be taken to the moon but it's gonna be way bigger. There will still moonbuggys also there's not gonna be a ceiling to the moon map because YOU'RE GOING TO ABLE TO GO TO OTHER PLANETS! Different planets are going to have different aliens. Some harmless. Some hostile. And some you just gotta make sure to not make em mad. Now, you're probably wondering how to get to these other planets. Introducing SPACE SUITS. Before you even take the rocket ship to go to the moon, there will be a buying stations and a new station where you can customize your space suits. The way the space suits work is that it would have a primary function and a secondary function and a flight/moment mode. I've came up with an idea for each of these.
Primary function: energy cannons
-not hitscan, straight trajectory
-if it directly hits a player, monster, or alien it deals 40 damage
- 20 damage for anything that's in the explosion radius (same as impact grenade)
Secondary function: energy beam
-holding both B and Y at the same time would activate the secondary function
- hitscan but not infinite range (range would be about the length of 5 lances)
- if constantly hitting your target, the target takes 70 per per second
Flight/movement
-press the bottom triggers to fly decently fast in whatever direction you're looking
Also, the space suits would be a permanently flying thing that you can control with your left joystick. Keep in mind that these are customizable and come with more options because those were just my ideas. Anyways, going back to the fact the you're gonna "need" these, you can use other movement items like the handheld jetpack, heart guns, hover boards, and etc. But the space suits are going to be very useful the kind of terrain the planets have. Every planet is going to have a horror aspect to them just like most of the other maps.
