ok well i'm going to go against the grain here, unless something is not right with my game ...
Bear in mind i've only played about half hour, but this is my impressions..
Firstly it's no Alyx, the 2d cut scenes are janky as.. and it feels as though you are in one every few seconds in the first 10 mins of the game..
ok getting past that, after the intro stuff, and onto the FPS section in the valley at the start, yes this is good, its does feel made for VR.. general controls good.. moving and running nice.. reload.. ok.. your hands look completely spazzed out when cocking the guns, but I can get over that.. also felt you needed to be very accurate with your hand position when doing this, which led to me having to try several times.. (never had this issue in alyx!)..
The aiming mechanics could do with some work.. i.e. I found it much easier to aim one handed than two, even with the sniper, and i'm not sure that should be the case.. found that too often I could see nothing down the scope two handed, and had to mess about with where my hands aligned to get any images at all in the scope.. yes this is possibly just a user issue..

.. but still felt very off to me.. one handed seems much simpler to get everything lined up.. but very wierd using a sniper rifle one handed..
ok that's the good and ok stuff.. finally got to the get in the large robot thing.. and oh dear...
firstly just the hmmm stuff.. the aiming / firing mechanics are just wierd.. left trigger - push forward - let go to fire rockets??? I mean wtaf?!?!?! i guess i could get used to it.. but felt very very wierd when first trying..
now onto the.. is this game completely broken... when i was in the robot, me looking straight ahead, was the robot looking towards the floor at i'd say an angle of about 20 degrees down.. to actually look straight ahead, i had to tilt my head upwards.. and as for looking up towards the top of the hills when in the valley, was my straining my head as far back as it would go literally 90 degrees upwards to look about 45 degrees up in game..
also turning felt disconnected, i.e. look left.. and my view looked inside the robot, and then after a pause the robot finally looked towards the left..
so is my game broken? is there some setting i'm missing? it certainly doesn't feel triple A at the moment.. more like a bad 70's B flick, where you can put up with some of the crap ness for some final overall enjoyment??
