Since the previous old versions of ksp forum has been closed to further replies, I've made a new one where you can download previously lost old versions of Kerbal Space Program. Some of the links in that previous forum (you can find it above) have become broken and no longer work, so I've archived them with (hopefully now) working download links. This also includes download links to some old versions I forgot to add in the previous forum (0.8.2, 0.13.1, etc).

As we all know, there used to be a forum where you could get old versions of KSP which is the one above. From February 2016 to January 2018 you could click on the links and download those versions. Now when you click on the links they redirect to the KSP Website and the versions were lost to time... But I have revived them! I have revived and retrieved KSP versions 0.7.3, 0.8.5, 0.9.0, 0.10.1, 0.11.1, 0.12, and 0.13.3 for download!!! (P.S: After downloading these versions I put them on my USB Flash Drive so they wouldn't be lost to time again!) I also have the 0.18.3 Demo on my USB Flash Drive! Here are the download links, Enjoy once again seeing how far KSP has come!: KSP v0.7.3: https://web.archive.org/web/20171214012934/https://kerbalspaceprogram.com/archive/0-7-3/KSP_win_0_7_3.zip KSP v0.8.5: https://web.archive.org/web/20171214004511/https://kerbalspaceprogram.com/archive/0-8-5/KSP_win_0_8_5.zip KSP v0.9.0: https://web.archive.org/web/20171214021804/https://kerbalspaceprogram.com/archive/0-9/KSP_win_0_9.zip KSP v0.10.1: https://web.archive.org/web/20171214023633/https://kerbalspaceprogram.com/archive/0-10-1/KSP_win_0_10_1.zip/ KSP v0.11.1: https://web.archive.org/web/20171214000815/https://kerbalspaceprogram.com/archive/0-11-1/KSP_win_0_11_1.zip KSP v0.12.0: https://web.archive.org/web/20171214022100/https://kerbalspaceprogram.com/archive/0-12/KSP_win_0_12.zip KSP v0.13.3: https://web.archive.org/web/20171214030829/https://kerbalspaceprogram.com/archive/0-13-3/KSP_win_0_13_3.zip KSP v0.18.3: http://i.download.idg.pl/fannef/1f39d38d83f0a3987a3541a2c07c2ee5/5ab80028//cyberjoy/pelnewersje/k/KerbalSpaceProgram/0.18.3/KSP_demo_win.zip P.S: I will add images soon of these versions as I begin to play them!
