When Isaac’s dad runs away and leaves him with his hardcore-christian mother, young Isaac finds himself with time to spare. So like any other normal human, so he plays a game. The game he plays is what you play, just with more blood. And a whole lot more realism. And a dead cat called Guppy. As you traverse through the underground, you fight off deadly monsters that come racing towards you trying to kill you! Or hug you. I didn’t hang around long enough to find out.

You use arrow keys to shoot and WASD to run about and to dodge certain death. E is used to drop a bomb, but beware: it drops directly at your feet and you can die from it. This game is about staying alive, just like every other survival game (duh).

The first thing you’re going to want to do is collect health. After that, I’d recommend you get upgrades. You don’t naturally regenerate health like that unrealistic game ‘Minecraft’. Health is really important, since without it you die. To collect health or HP you collect ‘hearth’, which gives you either ½ a red heart, 1 red heart, 1 soul heart or one evil black heart.

The aim of the game is to kill your mum (no joke). First kill her body, then you dive down into her uterus to kill her heart. Finally, you can either kill the lamb and Satan or yourself and blue baby. Killing all this with every character will unlock new and cool items for you to have fun with!
