No customizable layouts in Halo 5 unfortunately... You'll have to pick up weapons or use req weapons in war zone..how do you get the other assult rifles? right now it showing me having the first of 20 or so
In warzone: while at either a req station on on the respawn screen open the menu with Y choose the AR (since yore changing ARs) your other ARs are there. Note you may need to have a certain # of req level to use. They will not cost you any req energy.
If you have skins: open customization menu. Go to weapon skins choose the gun you want to skin. Chose a skin.
Note cosmetic choices carry over into arena.
To get more req items including skins and armor open req packs.
You earn them by simply playing and can buy them with the points you earn just by playing at the req store. You can sell req items for points. EVERYTHING CAN BE UNLOCKED BY SIMPLY PLAYING. If you dont have the time to play but want more req then you can spend $2-3 on bypassing the point system and getting a req pack.
Note even if you spend $100 on req you can get nothing but needler and mongoose. While some one who just played can get a tank. Even if you get a lot of good things the req energy system prevents pay to win. You cant send out tanks and mantis back to back unless you have the energy and the ammount you can have is the same as everyone else.
