History VideoGame / LostRuins

* BloodKnight: Kana, another human the Heroine can meet and assist, loves her katana and can tell the Heroine a story of how she enjoyed torturing a goblin by cutting off its fingers before killing it. [[spoiler:Her bloodlust eventually transforms her into a demon.]]

* AIBreaker: Sometimes, Rosie will just stand in place, until attacked, even when she's not tired out.

* ArbitraryWeaponRange: Magic Missile doesn't travel the whole screen.

** Eating the Mysterious Meat gives a permanent +5 increase to maximum HitPoints:
---> Has a remarkably unpleasant appearance.

* SpiderPeople: [[TabletopGame/DungeonsAndDragons Drider]]-like Spider girls are some of the tougher enemies one can encounter in the early parts of the game [[spoiler:and Heroine eventually fights one as a boss]].
* SupernormalBindings: The FinalBoss is [[spoiler:the Dark Lady]] with four shackles, which break away when defeated. [[spoiler:In the good ending, she reveals herself as the goddess Sadora serves, who Beatrice had imprisoned in the ruined castle to siphon power from.]]

* {{Doppelganger}}: One of the {{Apocalyptic Log}}s is an account of a girl who's been encountering enemies that have been mimicking her specifically, and the boss of the area you find them in is one of these beings while the original's corpse is nearby. [[spoiler:In the AnotherSideAnotherStory mode, the "Jun" part of the trio is also a Doppelgänger native to the ruined castle, which is why Kana and Yuri's souls are still trapped instead of returning to their original bodies.]]

* DoubleEdgedBuff: Hitting an enemy with the Cursed Scythe gives the Heroine a status that increases her damage given by 60% and attack speed by 1, but also increases the damage taken by 40%, and it stacks up to 4 times, along with all the buff stacks being removed if she misses with the scythe. But, taking off the scythe preserves the buff stacks.

** Shock Wave can knock arrows out of the air.

* HeartContainer: Mysterious Meat gives a permanent +5 increase to maximum HitPoints:
--> Has a remarkably unpleasant appearance.

* ChildrenInTow: The Spider moms give birth to [[MiniMook Spiderlings]].
* ClippedWingAngel: The Yuki-Onna boss starts as a huge giantess BackgroundBoss whose breath attack covers much of the screen; her second form is even harder, a giant (though smaller) floating lady who flies around summoning and attacking with giant ice crystals. If you beat ''that'', she proceeds to a third form... consisting of three tiny child-sized Yuki-Onna who throw slow, easy-to-dodge snowballs that do only a single point of damage if they hit.

* NintendoHard: The game is pretty unforgiving, with hard-hitting monsters, pretty limited healing, and the Heroine's capability to fight the enemies is frankly... pathetic. It doesn't help that is a rare {{Metroidvania}} where save points do ''not'' restore health and mana.

''Lost Ruins'' is a {{Metroidvania}} Action Survival game developed by Altari Games, an indie development team based in South Korea. Following [[https://www.kickstarter.com/projects/altarigames/lost-ruins a successful campaign]] on Website/{{Kickstarter}}, the publishing rights went to Creator/DangenEntertainment, and the game was released in May 2021 for PC through UsefulNotes/{{Steam}} and [[Website/GOGDotCom GOG]], with UsefulNotes/PlayStation4, UsefulNotes/NintendoSwitch, and UsefulNotes/XboxOne versions announced for later in the year.

* LethalJokeItem: The Throwing Ham. It's one of the few ranged weapons you can get with (effectively) unlimited ammunition and no real costs or restrictions beyond the need to retrieve it after throwing it. Getting it immediately trivializes most normal enemies, since they tend to be balanced around the danger of approaching them.

* BackgroundBoss: There are a few very large bosses that are fought this way, such as Lami's giant SlimeGirl form, YukiOnna, Mimic, and [[spoiler:the "Dark Lady" Beatrice summons]].

* HiddenMechanic: Before the battle, if you freeing a goblin hanging in Rosie's room then leave and return the room, the freed goblin is removed from the room, and therefore Rosie can't use them.
