Metal-Crete is still somewhat of a work in progress, after I noticed some well forged small maps being posted was then that I felt comfortable to just throw it out there for an idea. Though very simple, you may find it challenging once your opponent disappears, but what's it to you to fear a cloak when you have your over shield and brute shot? The smaller the map, the faster the game play, that is what Metal-Crete provides along with 4 basic weapons to choose from.
Battle Rifle: spawns in 30 seconds
Assault Rifle: spawns in 30 seconds
Plasma Pistol: spawns in 30 seconds
Brute Shot: main clip, spawns in 60 seconds.
It wasn't long before I seriously started debating how to place grenedes in which I came to placing only 2 of each found in the four main corners of the map.

Power ups are still in debate, I gave them the required treatments:
Over Shield: 60 second spawn
Active Camo: 90 second spawn
Considering to drop the Camo being that the map is so small, or could increase it to 120 second spawn?
That about sums it up, hope to hear from you awesome folks soon
