Here is my completed Valhalla remake named Fimbulwinter ( thanks to HannShotFirst for the name suggestion ). I tried my best to replicate the original Halo 3 map as closely as I could minus some weapon/vehicle tweaks. I replaced the bubble shield and the regen with 2 OS with a 120s respawn time and the brute shot is now a Hydra with a 60s respawn time. Every weapon on the map is the same as the original Valhalla and is located at the same place (BRs, SMGs, plasma pistols, rocket pods, laser, shotguns, snipers, etc.) with the addition of a few DMRs here and there. The banshees have been replaced by 2 ghosts and the mongoose by the turret is now a rocketgoose to compensate for this.
The map should work with slayer, strongholds and ctf, but if you find any bugs let me know as I have never tested the map yet due to the lack of friends I have who play H5.
