Over the years, John Tiller Software has had multiple publishers for the commercial games developed.
The early Talonsoft Battleground and Campaign Series wargames have been republished by Matrix Games who provides support for those wargames.
For John Tiller Software wargames published by HPS Simulations, use the support form below.
Note: Updates for JTS games will no longer be released through the HPS website as of 1/1/16. We have been migrating former HPS customers for 4+ years now, and the window is closing on that offer. If you have any remaining HPS cd's that you don't have a JTS serial number for please get your request in by June 30th, 2020. Proof of purchase is required and can either be through us searching the database for the original sales or through a picture of the original cd(s). To begin that process also use the form below. Serial numbers for every Tiller game published through HPS are being issued now.
**Note: Serial numbers will only be issued for original HPS cd's. There are pirated versions out there and we do not honor those. Be careful where you make your purchases.**
