addedSaves are now tamper protectedTo prevent false claims to those trophies, a mechanism to prohibit cheating had to be implemented. The mechanism is based on a simple trick: When a game is saved, a code is generated based on the state of the game. When the file is loaded and the code is wrong, then the file must have been tampered with. There is no third-party anti-cheat system involved. Saved games that were started before this update do not have such a code, thus are not protected against manipulation. For this reason achievements will not unlock until you start a new game.

changedOther changesLinux versions now include the OpenAL library. It was noticed that of all Linux versions tested, only Ubuntu did not seem to have it by default, so 'ldd' reported it missing. For some strange reason the game loaded up anyway, but only when launched through Steam. Must have been Valve magic...

Steam Achievements

There are now six trophies for you to achieve! They range from easy to hard to win. They are purely optional of course, the game itself did not change in any way. Trophies can only be won for games started after this update. The reason is described below. Sorry if that bothers you, but there is no other way.
