The simple action of a platformer with a touch of roguelike complexity. From the mind behind Starseed Pilgrim, Probability 0 takes the straight-forward yet challenging run n' jump gameplay of platformers like VVVVVV and stirs the formula up by applying the dynamically randomized levels, skills, and enemies of the roguelite genre (Spelunky, Risk of Rain) for an end result that is [b]infinitely replayable and impossible to master.[/b] The challenge in P0 is refreshing, while a lot of your runs will quickly end in your swift and humiliating failure the few runs you do make it far on will feel that much more rewarding and satisfying. There are loads of powerups to play around with all located on a large and expansive skill tree that you are able to upgrade between each level you manage to surpass. Every choice will have a huge impact on how you play and every player will find their own unique path of skills on the tree to succeed by. The game has a simple but abstract and almost horror l...

About This Game
There are a million ways to fight for survival.
Descend: as you combat the darkness, improve yourself. Build yourself up as a star-thrower or a teleporting menace. Learn to traverse the pit's many dangers, from threatening monsters to unforgiving gravity. Walk across spikes that once frightened you. Punch through walls that would have doomed you. You'll never be invincible.
Descend: enemies grow more numerous. They will destroy the floors beneath your feet, spit death at you, and cannibalize and infect each other in their mad swarming. Your foes will be invisible, or reckless, or explosive, or seemingly untouchable. Deeper dangers will always find a way.
Descend: and die, as you did last time and as you will next time. But find your way deeper.
There are a million ways to fight for survival. There is no way to survive.

Let's talk like people, now, and not like the back of a videogame box.
I designed Probability 0 years ago, and released its first version for free in late 2009. Back then, it embraced a randomly-generated landscape (so I wouldn't get bored of it), introduced higher-order enemies to the spawn queue in a random order (so I wouldn't get bored of them), and allowed you to buy upgrades from a vast and unrestrictive talent tree (so I wouldn't get bored of those). Oh, and death wipes everything (so I wouldn't just get everything... and then get bored of playing & replaying the whole thing).
On top of that, the enemies and powers are designed to be significantly different from one another. There's an enemy who literally eats other enemies and spits their digested corpses at you. (Mechanically speaking, their 'digested corpses' are always the same handful of red globs -- but what fun is it, thinking like that?) There are more mundane enemies, of course, but one who moves in random, erratic angles is very different to fight than one who always moves straight towards you.
The set of powers, on the other hand, were made to offer you a lot of choices. There are ~36 of them and contain nearly zero arbitrary prerequisites. Buy the powers you want to have, not the boring ones you'll need for the future. Every time you level up, a new row opens up and you can buy anything from any row except for abilities that build on a lesser version of itself -- you can't get the 'never take fall damage' powerup without first having the 'take less fall damage' one. There are also none that don't augment your choices in an interesting way. You're not choosing between +10% armour and +10% damage; who cares, when you could instead be choosing between immunity to every spike in the game and upgrading your punch to kill any enemy in one hit? Those aren't even top-tier powers.
I'm still not bored of this game, and remember that it started in 2009. There are boss enemies who appear intermittently, to shake things up. There are enough abilities to try thousands of different builds, if you're feeling a little stale. There are enemies who don't even appear until you've gone deeper than I can most of the time. You'll probably die before seeing any of these things, but don't let that stop you. Keep dying.

Don't forget about queenjazz's dynamic music. Its layers fluctuate as you dive deeper: the bass comes and goes; the chords swell and die; and the sirens scream as death approaches. You can hear it in the trailer, in the game itself, and even more by looking up the soundtrack on bandcamp.

Great idea. Seems like it could be really addictive. Unfortunately no controller support, and despite the fact that its a small flash game, it performs really horribly on a Mac. Its got to be software bug in their flash player. It has a low framerate, and is very sluggish, making it unplayable.
It's certainly not anywhere near the worst game I've played. It's just that the combat, which is sort of essential to the gameplay, feels really bad. I realize the entire point of the game is to get further by upgrading, but you start off so terribly weak and frail that it's hard to really make any progress. I think some people will probably love this game, but I personally cannot recommend it.
This game is one of those Forerunners during the early 2010's indie game craze. I played this game a lot then. Just bought it on steam cuz i missed it. The few small complaints I have are easily overlooked next to the amount of fun and replayability the game offers. (incase you are completely helpless, get a gamepad mapper! this does not have gamepad support) Good platformer, cool music, skillz required
10/10 would die again. Probability 0 is the basic concept behind roguelikes boiled down to a very few key aspects, and mixed with some clever design elements. It's pure, accessible, deep, and has an eerie, mysterious vibe to it. The platforming and combat both start out really simple, and are continuously expanded upon through new abilities (like firing your ranged projectile in new directions, being able to stomp your enemies, smash otherwise solid blocks, just to name a few). It's worth mentioning that the skill tree is extremely refined and well-designed. It feels balanced, interesting, and allows for an astounding amount of customization and experimentation at the same time. Enemies start off really simple, but as you get deeper, the spawn pool gets mixed up with very interesting critters that drastically differ in their movement, attack pattern and other behaviour. Since each enemy and environmental hazard is extremely easy to grasp and learn, death is rather caused by multiple ...
Severely underrated, bombastic music and endless replayability. KNEES SHOULD BE A PASSIVE NOT AN UPGRADE THOUGH SERIOUSLY GUYS THE FALL DAMAGE HURTS SO BAD.
I picked this up on Steam a few days ago and have become slightly obsessed with it. as in, I am hearing the music in my dreams at times, and find myself humming it as I go about my day. it's a lovely, quite melancholy trip into the abyss, in which a hapless fellow bounces about, shooting stars and trying not to run out of probability. I'll explain that last, later. there are three game modes -- in Beginner, the object is to scatter as many foes as possible. in short, kill them without mercy. in Expert, it's depth that matters -- delve as deeply as possible before your chances run out. oh, and you should probably still kill things, so you can level up... but the depth's the real thing here. I'll get to the third mode in a moment, because a bit of explanation must come first. when you destroy enemies in either Beginner or Expert, an experience orb appears. sometimes it's JUST experience. sometimes it comes with 3 or 6 shots of your star. sometimes there's a little heart inside, w...
Parallel Universes in which this game is bad 0
I absolutely love this game. It's a great time-waster and no matter how good you get, you'll come to the realization that we all equally suck at it. But it's a fun kind of suck. 10/10 will play forever.
[b][i]Probability 0[/i][/b] is a procedurally-generated infinite platforming game with roguelike elements. The only real goal of the game is to survive as long as possible as the game automatically scrolls downwards. You build up a score based on the number of monsters you defeat while descending, and you level up with the experience points that the monsters drop. Leveling up gives you new skills that will increase your chances of survival, but the odds are always stacked against you. In fact, there's 0% chance you'll beat the game. The gameplay is very simple, but tough to master. At the start, your combat abilities are shooting stars beneath you while airborne and punching. Both are pretty weak, but as you gain new skills, you'll become more formidable. There's a wide variety of monsters to face, each with unique patterns and abilities. Touching them knocks you around unpredictably, exposing you to other dangers below. If you get far enough, you'll even face tough boss enemies! The ...
