Killzone Mercenary first impressions

Could the PSVita fps curse be over?  It looks like it could be with Killzone Mercenary a game that I am being cautiously optimistic about.  Playing the multiplayer beta has made me hope again for console quality gaming on the go.  Because let’s be honest the most console quality game on the vita at the moment is Uncharted Golden Abyss.  Killzone Murcenary’s multiplayer is almost console fps multiplayer, almost.  The biggest problem is that the Vita’s touch functionality is integrated into the multiplayer with no way to bypass it.  There are some things that use both controls like sprinting can be done by ether tapping the back touch twice or by pressing the circle button.  But the biggest disappointments are the special powers like launching missiles or orbital bombardments.  These have to be done with the touchscreen and it is awkward.  Sure it sounds cool to just simply tap the screen and watch your enemy get blown to bits but in the heat of the moment I just resorted to madly tapping at the screen only to be shot by the guy who is using real buttons.  Having unavoidable touch functionality in the end just breaks the biggest rule of fps gaming: your thumbs should stay on the joysticks as much as possible.  At the moment the only cool touch control is melee attacks.  If you are attacked by melee from the front everything goes in slow motion and you are given a split second to counter the melee attack, by swiping the touchscreen.  This works because after you swipe the touchscreen you are given enough time to put your fingers back on the controls before time resumes normal speed.  However, when you don’t have to use touch controls the joystick controls feel good and aiming down the sights is not finicky.  In the end I have a overall good feeling about Killzone Mercenary and I am interested to how it is received when it is released this September.
