but there are combos that u can use to kill the monsters.
get close to the enemie and press x, square (x2) or x, square, triangle.
in some enemies u can use these techniques

shadow95 is wrong press l1 lots of times but you can only do it 2 times in the game. it
goes super slow motion and you go invisible and you will not have any sand tanks left. it
dosent always happen.
