This is a version of the original mod with an update that makes it compatible with the 2.0 version of the game, as it hasn't been touched in over a year. At the original creator's request, this can be taken down. I've no experience with modding Factorio in particular, so this was a quick and dirty edit to the info.json. No other edits have been made. Original description follows.

This mod adds a bunch of new sounds for your programmable speakers.

Bonus sound: Bells for railroad crossings (Transport Tycoon style, of course)
Sounds:

3x Generic alarm sound
3x Machine/Factory alert
2x Evacuation alert
2x Intruder alert
2x Sirens (one long, one short and ongoing)
1x Nuclear alert
1x Gate warning
1x Alert bells
1x Railroad crossing bells

Please see the attached credits file for a detailed track list. Some of the used sounds have been modified by me (i.e. shortened), but i do not own any of them.

Most of them are licensed via CC-BY-SA 2.0, but feel free to contact the creators if you would like to use some of the sounds for a project of your own. To support the creators, please do not distribute the sounds separately from this mod, but use the originals instead. Thank you!
