Undertale Last Breath

Undertale: Last Breath is a fan game of the original Undertale and does what the original developer of the game didn’t dare do any further, and that’s ramp up the difficulty to exponential levels! The game was originally released on the 14th of September 2019 by ZerJox, but has seen several updates since then to keep the game up-to-date.

The Game Review


As already stated, Undertale: Last Breath is a fan-made version of Undertale that takes the idea of the already difficult fight against Sans and then increases the difficulty all the way up to 11! The game is designed to be no joke and the worst part is that there are 3 different phases/difficulties for Sans, so even if you do manage to beat him the once, it doesn’t mean the other 2 are going to be any easy. Depending on how hard you like your video games, you may love this or you may hate it – it’s really dependent on if you have the patience to pick up all of the bosses’ patterns.

When it comes to the actual gameplay, it’s all very simple – even more so for anyone that’s played or beaten the original Undertale. Your job as the player is to simply survive the bullet-hell onslaught that is Sans. You’ll be in control of a little heart that needs to constantly dodge every single laser, bone, and damaging effect that comes your way, all while the speed relentlessly increases.

If you manage to survive, you can progress further into the game and take on the increasing challenges until you get the eventual ending. Thankfully, though, the exceptional music through the hard times will certainly make each defeat a bit easier to muster.

There really isn’t much complexity in how the game is handled, but damn, does it quickly get intense right from the word go. To progress in the game, you’re going to need to learn San’s patterns as best you can. Outside of this, though, there really isn’t much more to the gameplay as a whole, so for anyone that doesn’t enjoy dodging a barrage of bullets at break-neck speeds, this one probably isn’t going to be for you then.


Undertale is one of those games that have a very iconic pixel-art style, so it needs to be delicately addressed by the developer to ensure that they don’t do too much or too little to take away from the visuals. Thankfully, Undertale: Last Breath does make some small additions to the game’s graphics, but it blends well with Undertale’s aesthetics, without being overbearing or overshadowing at all.


Everyone knows that Undertale has a phenomenal soundtrack that is still talked about years later and for a very good reason. Just like with the graphics, it would be really easy for the developers to do too much or too little and end up subtracting from one of the game’s biggest strengths, but thankfully that isn’t the case at all. Right from the very moment you play the game for the first time, you are treated to the game’s soundtrack, and as things get more intense, it just ramps up from there and gets better and better.


Overall, Undertale Last Breath is a great continuation of the ending of the original Undertale while making the game a lot more challenging. By any chance you’re looking for some more Undertale and want something a bit more difficult, this is the Undertale fan game for you. At no point is the game considered easy, but with a bit of practice, while enjoying the fantastic audio, you’re in for a great time.
