I really wish i had Index controllers for HL:A. Im finding the Vive ones awkward to hold for a prolonged period of play and i keep pressing buttons i dont mean to and find holding the triggers uncomfortable. Ive taken about a million screenshots because i keep hitting the two buttons at the same time.
Ive just got the grenades which are fun but a few times ive not been able to coordinate the buttons and end up dropping it at my feet and then having a mad scramble to pick it up and lob it.
