First things first. Look at this gif of the map's loadout camera.
Now that that's out of the way, Lumen is an asymmetric 2v2 map. This is the only original design I've made so far that I really like.
Weapons and Powerups are
-Neutral Overshield in the middle
-Sniper for each team. It spawns behind their initial spawns.
The map has a tunnel in the center that acts as a quick route to get from base to base. However, anyone who uses it will be incredibly exposed.
Players will be able to see each other through the tunnel and this leads to very interesting long-range BR battles that can either lead to someone getting taken out from afar or lead to players pushing up the map through either one of the atriums.
The atriums are also linked to the central tunnel in their own way. Red atrium brings players closer to the lift that then takes them to the central tunnel. Blue atrium allows players to be able to shoot into the middle of the tunnel.
