Risk of Rain -
When you get in game, it will tell you what map you are in, I landed in Desolate Forest, and it will show the controls. space is to jump, arrow keys are to move, and zxcv are for the corresponding abilities. Z is your basic attack, it has no cooldown. X is a piercing shot with knockback, it goes through everyone in a line infront of you, it has a 3 second cooldown, I would recommend using this in combat whenever possible. C is a roll, while rolling you don't take any damage and it sends you forward a small distance, it has a 4 second cooldown, I would recommend using this in combat to avoid attacks while you wait for your other cooldowns, and to travel faster. V is another attacking ability, it can hit both sides of you, and it stuns everyone hit by it, this has a 5 second cooldown, I would recommend using this whenever seems applicable.
