Here's a summary of what to expect soon:
Free For All Titanfall 2 Players
- New Map: Colony. This classic should be familiar to long time Titanfall fans. Set among a sleepy settler town, the dense center is filled with narrow streets, interiors, and rooftops surrounded by open Titan lanes.
- Weapon: R-101. Universally well regarded for its unique versatility, the R-101 platform has been a mainstay of human conflict since the first settlers arrived from the Core Systems. This version is outfitted with ACOG scope.
- New execution: Curb Check.
- Prime Titans: Northstar, Legion.
- Titan Art Nose Art: 5 new designs, 1 new Warpaint per Titan
- Camo pack: 20 camos
- Callsign pack: 20 banners, 20 patches
In addition to the above there will also be a patch with a plethora of bug fixes, balancing, and game improvements. We’ll be releasing full patch notes closer to launch.
