In his latest progress report on the title, Craig Stern has seen fit to let us know that he decided to add a single-player campaign to the until now strictly multiplayer Telepath Tactics. Unfortunately it's going to be fairly linear, but considering the title wasn't supposed to have one in the first place, you can't really hold it against the developer:
Now, I know I said in the last update that a campaign mode was not a top priority, but I’ve gotten enough feedback since then demanding a campaign that I’ve decided it would be silly not to put one in the game. This has meant a few weeks away from coding the multiplayer, instead putting in things like a dialog system, cut scene support, and support for custom named characters. I hate to take so much time away from multiplayer, but it’s hard to argue with the results.
In the interests of keeping development time down and allowing me to return to finishing up multiplayer, the campaign mode is going to be extremely linear, and probably not all that long. However, I’ve already added single player map support to the Map Editor, meaning that you’ll be able to modify or extend the game’s campaign yourself! I am also considering the possibility of adding proper support for multiple custom campaigns to the game. We’ll see how it goes.
