Titanfall 2 will have a new mode called Coliseum. It’s an opportunity to go into a best-of-three fight against one other player. Each of you is in their Titan and has a chance to go all out, with the winner getting Callsigns, Camos, and other Advocate Gift rewards. But, to get in, you might need to buy some junk food in the real world.
See, you need a ticket to get into Titanfall 2’ s Coliseum. You can get these from playing multiplayer matches or by getting Doritos, Mountain Dew, or stuff from Buffalo Wild Wings. Grabbing Doritos or Mountain Dew may be the best bet, as their codes give you a ticket, double XP and will give you things like a Ronan Titan, Camo, or Warpaint.
At least this Titanfall 2 promotion isn’t too bad. Sometimes, offers like these tie exclusive customization option DLC to products. You have to buy them to get the items. Even though there is a chance of getting other items from these codes, everything can also be acquired for free in-game.
