I'm unfortunately a bit late with this announcement, but if you ever wanted to give Titanfall 2's multiplayer a shot you now have a chance to do just that. Until Monday (April 3rd) you will be able to experience the entirety of the multiplayer mode for free, as well as the Training Gauntlet and the singleplayer mission "The Beacon". Once the free weekend event goes away you will no longer be able to play the multiplayer, but you will still be able to mess around in the Training Gauntlet and The Beacon.
Besides the free weekend the most recent update has also brought in a brand new map by the name of Colony, a new versatile assault rifle, and an execution move that seems greatly inspired by Mortal Kombat's Scorpion. If you're interested in seeing what this looks like in gameplay terms, here's the recently posted preview trailer:
And that's pretty much everything you need to know before jumping in. Have fun!
