Seven days. That is all you get. When Shin Megami Tensei: Devil Survivor first landed on the Nintendo DS back in 2009, it didn't just feel like another spin-off of the massive Megami Tensei franchise. It felt like a panic attack in cartridge form. You're trapped in the Tokyo lockdown, the government has basically quarantined everyone to let them die or be eaten by demons, and your electronic devices are suddenly predicting exactly when your friends are going to kick the bucket.
It's heavy. Honestly, most tactical RPGs are about moving units on a grid and optimizing stats, which this game has in spades, but the actual "vibe" is what sticks. It's the claustrophobia. You aren't a legendary hero traversing a vast fantasy world. You're a teenager in a hoodie trying to find a way out of a subway station while the world ends around you.
The Brutality of the COMP and the Death Clock
The core hook of Shin Megami Tensei: Devil Survivor revolves around the Communication Player, or COMP. In the game's universe, these are modified handheld gaming devices that allow humans to summon and control demons. But they do something much worse: they show a "Death Clock" above people’s heads. If you see a "0" over your best friend's head, it means they are dying today.
You can't just ignore it.
Every action you take in the menu consumes time. Moving from Shibuya to Akihabara takes thirty minutes of in-game time. If you spend too much time grinding for Macca (currency) or chatting with a specific NPC, you might literally run out of hours to prevent a murder. It’s a brilliant way to merge the narrative stakes with the actual gameplay loop. Most games tell you there is an "emergency," but then let you go fishing for twenty hours. Devil Survivor will actually let your favorite characters die if you're lazy.
The demon summoning system is where the "Megaten" DNA really shines through. You aren't befriending these creatures through the power of love. You're bidding on them in a literal eBay-style auction. If you want a powerful Helel or a chaotic Loki, you better have the cash and the guts to outbid some random NPC named "DemonLover69." It adds a layer of grime to the experience that fits the apocalyptic setting perfectly.

A Different Kind of Strategy
Traditional Fire Emblem fans might find the combat here a bit jarring at first. It’s a hybrid. You move your squad—consisting of one human leader and two demon companions—across a grid. When you initiate an attack, it shifts into a classic first-person, turn-based battle.
This creates a weirdly deep layer of strategy. You have to worry about "Extra Turns." If you hit a weakness, you get another go. If you get your weakness hit, you lose your turn. It’s the Press Turn system from Shin Megami Tensei III: Nocturne but condensed into a tactical format.
One thing people often get wrong about this game is thinking it’s just a "Persona-lite." It isn't. While Persona focuses on the power of friendship and high school life, Devil Survivor is much more interested in social Darwinism and the breakdown of law and order. When the water runs out and the demons start circling, your "friends" might actually turn on you. The moral choices aren't just "Good vs. Evil." They are "Control vs. Chaos vs. Just Giving Up."
Why the Overclocked Version is the Definitive Way to Play
If you’re looking to dive into this today, you’re probably looking at Shin Megami Tensei: Devil Survivor Overclocked on the 3DS. It’s basically the "Director's Cut." They added full voice acting, which is surprisingly decent for a 2011 localization, and an "8th Day" that expands on the endings.
The original DS version was notorious for its difficulty spikes. Beldr. If you know, you know. That boss fight is a literal wall that has caused thousands of players to drop the game. Overclocked adds a "Satan" difficulty (Easy mode) if you just want the story, but the real meat is in the "Compendium." Being able to summon demons you’ve previously owned makes the mid-game much less of a slog.

The Art of the Demon Auction
Let's talk about the economy. In most RPGs, money is an afterthought. In Shin Megami Tensei: Devil Survivor, you are constantly broke. The auction house is a fickle mistress. Sometimes you can snag a high-level creature for a bargain because the other bidders glitched out, but usually, you're scraping together every bit of Macca just to fuse a demon that doesn't die in one hit to an Agi spell.
Fusing is the heart of the game. You take two demons, smash them together, and get something stronger. But the twist here is "Skill Cracking."
To get new abilities for your humans, you have to "mark" an enemy at the start of the battle. If that specific character defeats that specific enemy, they "crack" the skill and can now use it. It forces you to play aggressively. You can’t just hide your healer in the back; if the enemy healer has a "Media" spell you need, your healer has to go get their hands dirty.
The Philosophical Weight of the Endings
The game features multiple endings based on who you side with. Naoya, your cousin and a total nihilist, wants you to become the King of Bel and overthrow God. Amane wants you to establish a kingdom of peace under divine rule. Yuzu just wants to run away and hope for the best.
The "Yuzu Ending" is actually one of the most interesting because it's the "human" choice. It’s cowardly, realistic, and has devastating consequences. Most games punish you for making the "wrong" choice, but Devil Survivor just shows you the fallout. It treats the player like an adult who has to live with their decisions.

It’s worth noting that the character designs by Suzuhito Yasuda (known for Durarara!!) give the game a very specific look. The characters look sleek and modern, which contrasts heavily with the grotesque, traditional demon designs by Kazuma Kaneko. It creates this visual tension—bright, pop-art humans versus ancient, mythological nightmares.
Survival Tips for the Tokyo Lockdown
If you are starting a fresh save, there are a few things that will save your life.
First, focus on the Magic stat for your protagonist. In almost every Megaten game, Magic is king. Physical builds can be fun, but being able to exploit elemental weaknesses is how you win the action economy. If you can't hit a weakness, you aren't getting Extra Turns, and if you aren't getting Extra Turns, you're dying.
Second, don't ignore the "Race Skills." Every demon belongs to a race—Avian, Beast, Deity, etc. These races have unique field abilities. Avians can fly over obstacles. Beasts can move twice. Wilder demons can attack from a distance but can’t move after. Mixing and matching these is more important than the actual stats of the demons. A weak demon with a "Flight" skill is often more useful than a powerhouse that gets stuck behind a fence.
Third, keep multiple save files. This is a game from an era where "soft-locking" yourself was a real possibility. If you go into a story battle under-leveled or without the right elemental resistances, and you only have one save file inside the battle prep menu, you might be stuck.
Final Practical Advice
- Prioritize the "Movement" skills: Getting your units across the map quickly is often the difference between saving an NPC and watching them get devoured.
- Abuse the Free Battles: If you're stuck on a boss, don't bash your head against a wall. Go to a Free Battle, crack some skills you missed, and fuse something that reflects the boss's primary element.
- Check the Lap-top: Talk to everyone. Even if it doesn't advance the clock, the flavor text often gives hints about upcoming boss mechanics or hidden demon fusions.
- Don't be afraid to fail: Your first playthrough will likely be messy. That’s the point. The New Game Plus mode allows you to carry over your demons and skills, making subsequent runs much faster so you can see the other 5 or 6 endings.
The beauty of this game is that it doesn't hold your hand. It trusts you to manage your time, your money, and your morality in the face of an impossible situation. Whether you're playing on an old DS lite or an emulated 3DS, the tension remains exactly the same. Tokyo is falling, the clock is ticking, and you've only got a few days to decide what kind of god you want to be.
