About Nancy Drew®: The Deadly Device

Discover true facts about Nikola Tesla, an eccentric physicist and inventor.



Fear lingers in a remote laboratory after a physicist's suspicious demise. A police investigation resulted in nothing except a case as cold as the secretive personalities and steel walls that enshroud a top-secret Tesla-inspired facility. That's why the lab owner asked you, as Detective Nancy Drew, to expose the terrifying truth about The Deadly Device!

This was a fun one! It was hard, but I did enjoy the puzzles. Wrecked my sleep schedule on a work night having an absolute blast.

One of the best games they have! I love the whole lab setting, and you get to battle wits with Mason lol. Ryan is such a cute character.

One of my favorite Nancy Drew games I've played. Fun thematic puzzles and everyone's a suspect. Lots of gameplay that doesn't drag (unless you get stuck when you can't find a necessary clue lol)

Nancy Drew: The Deadly Device is an engaging detective adventure that combines mystery, science, and puzzle-solving into one of the more memorable entries in the long-running Nancy Drew series. Developed and published by HeR Interactive, the game places players inside a sophisticated research laboratory where renowned physicist Niko Jovic has died under suspicious circumstances. Although authorities have ruled the incident inconclusive, Nancy Drew is called in to investigate, uncovering a web of hidden agendas, professional rivalries, and carefully guarded secrets. The game's emphasis on investigation over action creates an experience that rewards curiosity, patience, and logical thinking. The laboratory setting gives The Deadly Device a distinctive identity compared to many other games in the series. Inspired by the legacy of inventor Nikola Tesla, the facility is filled with experimental technology, advanced security systems, and scientific equipment that all contribute to the authenticity of the environment. Every room feels purposeful, encouraging players to thoroughly examine their surroundings in search of clues. Rather than relying on haunted locations or supernatural event…

maybe the oddest Nancy Drew game i've played. the mystery is really bizarre with its more "scientific" angle and the setting is extremely small - maybe the smallest out of any Nancy Drew game i have played. you are in a small research lab in a snowstorm and you can not leave because of that, so you will get to know about five rooms very intimately. this lends itself to a small cast, but unlike most Nancy Drew games with a small cast i think all of them are really interesting, here. one of the only games in this franchise i've played where i genuinely was unsure as to who the culprit was for any period of time - usually it just jumps out at you immediately! weird puzzles that i think are gonna be hit or miss depending on who you are. it isn't anything ACTUALLY scientific but you will be referring to binary translations and the periodic table and circuitboard diagrams a lot more than you will be in any other Nancy Drew game, that's for sure. maybe not my favorite kind of puzzle but some may really like that kind of thing.

Worst game ever! The puzzles were complicated, especially the candy machine. Some of the characters were unlikable.
