Guide to Lock On/Target Enemies
Game only has a slight “soft Lock”. Press R3 when targeting a enemy, they will have a white rectangle about them but all it really does is focusing the camera more onto that enemy, you can still hit other enemies and must manually adjust.
Its pretty much worthless as a lock on.
In the first options tabs there are two options pertaining to this.
Soft Lock and Lock-on. They are two different things.
If you want a more traditional lock-on feel, disable the soft lock and leave the lock-on, on.
IIRC Lock-on is off by default.
