Respawn and EA have officially announced the dates for the Open Titanfall 2 Tech Test, which will be available on PlayStation 4 and Xbox One. The Tech Test will not be available on PC.

Tech Test Dates:

#1: Aug 19-21
#2: Aug 26-28

For the first Tech Test, these are the maps and modes available:

MODES:

Bounty Hunt (5v5): A brand new mode that pits Pilots and their teammates against an opposing team as well as the Remnant Fleet. Earn bonuses by killing grunts and enemies, but make sure and deposit all your points at the bank between waves without getting killed.
Pilots vs. Pilots (8v8): Players can be the best Pilot on the Frontier and put their combat and mobility skills to the ultimate test in this classic 8 vs 8 Pilots only mode.

MAPS

Boomtown: A secret underground IMC facility where the latest in R&D is put to the test. In this facility Pilots can use the many peaked roofs to use as cover against combatants below. With tight lanes through the middle, Titans can also be easily ambushed.
Homestead: The IMC have claimed Imminent Domain on a small commune’s plot of land. With a series of raised, rocky plateaus and a river running down the middle, Pilots are mostly safe from Titans among the rocks and trees but they also can duck into the caves and building when needed. However, the Titans control the large rolling fields.

For the second Tech Test, the above content will be included with an additional map and mode:

MODE

Amped Hardpoint (6v6): A new twist on Hardpoint Domination from the original game; now defending a Hardpoint will let you amp it, giving your team double score. Team work is the key to securing victory.

MAP

Forward Base Kodai: Militia forces have taken over an IMC substation and set up a forward operating base. Pilots can find safety from Titans in the hallways and chambers of the main building, while Titans can walk over the roof to get a better view of the action.

8 vs 8 for Pilot v Pilot, seems ditching last gen has allowed them to up the player count.

Got a beta code! Installing now.

Is this an open beta?

Yes.

But some twitch users and various Respawn employees are giving early access codes out for both platforms. Otherwise, everyone can download this Friday, and again next Friday.
