This is a competitive remake map reimagined in Halo 4. It's simple enough to follow, it's non random weapons with other weapons scattered around in your base, each team gets a bunch of armour abilities, two Shotguns, DMRs, a sticky detonator, plasma pistol, rocket and sniper but they all have limited ammo with medium respawn times so don't waste the ammo. Also each teams gets a mongoose. Here is a neutral banshee in the middle.
My Advice: Don't go for the banshee at the start as it gets chain hijacked until it is destroyed, my advise stay back and try to hold the middle where the banshee spawn is as it pushes the other team back plus just throw your grenades as you leave your base.
Requires a custom gametype: Classic CTF adaption
Credit goes to Xerbase for the original idea for this in Reach
If you remember any spots or are rewatching the video of it to find some techniques it's called Frontline and it was reviewed on THFE. Good Luck Getting That Flag...
