Alright, I've spent about two hours playing. The game plays completely different than TF1.
The map design has moved the wall running from the forefront of the gameplay to just being a movement capability. I don't feel like I can traverse the map anymore via wall running the way these two maps are designed. The smaller map in this open beta has random obstacles that either obstruct your vision or get in your way of wall running.
The bigger map has huge open areas, but like zero zip lines as you would see in the first to help traversing the map.
Base movement is slightly slower.
Gunplay still feels tight like the first which is great. Not a fan of the change of weapon load out. In the first you had a main, a sidearm, and a anti-Titan weapon. Now you have a main and choose between a side arm or anti-Titan.
Titans are kind of meh.
I think making specific Titan classes using specific weapons was the wrong way to go. They should have kept all the customization from the first, made the "special move" Titan specific, but still allowed the use of whatever weapon you want.
I feel like the Titan vs Pilot game play has been changed for the worse. The whole remove the core then and automatically being thrown off then having to jump back on the Titan is kind of lame. Because the removal of Titan load outs, also feels like when a pilot rodeos your Titan, there is little you can do.
Titan v Titan gameplay has also fundamentally changed as it is no longer a dance if that makes sense. I don't feel like I can take on multiple Titans in this game like you could in the first one.
I feel like you have to play Titanfall 2 more like CoD so far. You have to be more conservative in your map movement. People called Titanfall Cod with Mechs before it released, and they were wrong, This feels like CoD with mechs.
