When it comes to Damnation remakes, you have the good, the bad, and the ugly. But of all the other maps I'm aware of, none are perfect 1:1 recreations of the original. Ole Kirk Christiansen, the founder of the Lego company, once said, "Only the best is good enough." I happen to agree, and therefore I went ahead and remade Penance from the Halo Reach Anniversary DLC, and built it as close to the original as possible both in terms of scale and aesthetics. There are actually two versions of this map in my fileshare: "Damnation" and "Reconciled". The difference between the two is the weapon sets and spawn locations. As you might guess, Damnation is set up for classic, while Reconciled is mean't to mirror the Reach version with the red and blue spawns flipped and slightly different weapon placement. Both can be played with all modes, including Arena Breakout, however I strongly advise that you play with spartan abilities turned off unless you're playing doubles.
Created by SmoknBrlz64 (Smokin' Barrels) with some inspiration from N3gat1veZer0's Damnation remake, "Atonement".
