This is Castlevania in 3D done right.
The game would take place at the start of the Castlevania timeline. Leon Belmont's beloved is taken away by Walter, an evil vampire count. Leon rushes to her aide and comes across Rinaldo, a man that lives on the outskirts of the castle and lends him the Alchemy Whip, a weapon capable of damaging vampires and related demons. The story is nothing special, but it gets the job done... the writing is really bad though. Dialogue falls under the "so bad it's good" category, so at least it's not a total train wreck.
Combat is very straight forward: Square performs a weak, but fast, swing of the whip, while triangle performs a stronger and slower attack. There's a fair amount of combos that you can perform, and as you defeat enemies you'll earn new ones, don't be mistaken though as there is no leveling up system, you just earn new moves every now and then. Leon also has access to all the classic sub-weapons, the Axe, the Knife, the Holy Water, the Cross and the Crystal, which consume hearts that are obtained from breakables. Each of the five orbs, plus two hidden ones, alter how sub weapons behave, so there's a huge amount of different sub-weapon attacks. Rounding up his arsenal, Leon's enchanted gauntlet can absorb MP by blocking enemies magic attacks, and can then use MP to activate Relics that bestow many different abilities. So far so good, but for some reason they decided to make menus work in real time. You can't pause and use items or equip items, instead, you have to use the right analog stick to navigate menus, using healing items during boss battles can be very annoying.
Lament of Innocence lasts a solid 6 hours, and that's what it took me to 100% it, every item and hidden boss found and defeated, but, finishing the game unlocks plenty of extras: Crazy Mode(A harder game), All Skills(Get all skills from the start), Joachim(An alternate character that plays NOTHING like Leon), Pumpkin(A character that shares only the basic moveset with Leon, he gets his own exclusive sub weapons and playing as him actually feels different) and a couple of others. Suffice to say, what it lacks in length it makes up in extras.
8.0 out of 10.
