classic is good, but the puzzle seems unlogic, i tried to make stuff that were part of the "details" filled in when i completed it, that got quite frustrating
how to miss with a grenade launcher? a. you dont aim high enough so it comes in front of the enemy, exploding harmlessly b. the monster ducks, grenade lands behind him, exploding harmlessly c. ya shoot plainly up and headshot yarself d. ya hit a falling tree e. yar grenade doesnt explode f. the monster grabs a tennis racket and throws it at the grenade so it explodes too early etc. (yep, ya have to use small explosives or else ya kill yarself)
achievements link to other site, this is odd, but more importantly, i get forced to take this road, kill an enemy, return, open gate, kill some enemies, return to first spot again, it all feels like a movie, not like a game, the player has no influence, he just follows a predetermined road.
