Risk of Rain is a sci-fi, rogue-like platformer with hardcore difficulty. The rather vague story starts off with an unknown entity destroying your ship and everyone on it, except for yourself. Playing as one of the ten unlockable characters, you have to fight your way across the planet and slay the one who did this to return home.

The game consists of you playing only as the Commando, a character with unlimited range and piercing attacks. You need to collect items to power-up and survive the fatal planet, and to hurry alongside the time so you won't get swarmed by hordes when you are too weak to fight back. There are six stages, each having two totally different stages, and both have 'variants', which change some parts of the map and whether or not you can obtain 'artifacts' to change gameplay. The only two stages with one map are stage five and six. However, as you unlock achivements, you'll unlock more items and more characters to play as. Each character requires a different way to play, which increases your horizons as you unlock them. The only way to move to the next stage is to activate the teleporter, which brings on swarms of normal enemies and then a boss monster. Once you kill them all and survive the duration, you will be able to move to the next stage.

Another main function is permadeath, where if you die, you die forever. You'll have to restart from the very beginning, and this is a main reason why you do not want to let the timer build up.

This game is also avaliable to play on Multiplayer, with 10 people max on each server. If you desire to play on my server, just ask me. In Multiplayer, aside from the obvious elements, you can die in a game and not suffer from the effects of permadeath. Once the surviving players move on, you'll be revived.

There are five tiers of items, which are colour-coded.
- The first one is Common, which uses a white border to signfy it. This, of course, is the most encountered tier.
- The second is Uncommon, which uses a green border to signfy it.
- The third is Boss, which uses a yellow border to signfy it. This are only obtained from killing boss monsters.
- The fourth is Use, which uses a orange border to signfy it. You can carry only one, and the rarity for each item varies.
- The fifth is Rare, which uses a red border to signfy it.
- The sixth is Special, which uses a purple border to signfy it. These are only avaliable in two stages in the game.
