If we receive more maps in future updates, I think the Forerunner stuff could receive a bit more focus. Especially for Warzone, I would love to see a map based on Kamchatka and the Forerunner facilities seen there, alongside another snowy map. (Prior to this, there is only one Forerunner structure in Warzone; and it’s the structure on Raid on Apex 7.) Of course, some more Forerunner maps for Arena are welcomed too. Maybe something a little more open, given that Tyrant was very small and closed-in.
I wouldn’t mind seeing a Coliseum remix that was actually modified considerably from the original.
Make it an asymmetric environment… add new jumps and geometry… make it a more dangerous map to traverse, with death pits or suspend the map and its routes entirely over a chasm.
Make the bases two floors… lots of possibilities, just don’t take the easy way out like most remixes.
