Recommended:

OS: Windows 10 (why not recommend the newest?)
Processor: Got four cores? Great! Bit Blaster XL will run smooth on most things, but especially on four cores.
Memory: 2 GB RAM
Graphics: 512mb +
Storage: 300 MB available space
Sound Card: I made a bunch of the sound effects by making stupid noises with my mouth into a pretty low rent consumer microphone, so I recommend not having a sound card, or you may realize this.
Additional Notes: When you do things right, people won't be sure you've done anything at all.
