The 1.02 release of Microsoft Hellbender Trial contains all the intense action of the original trial version with significant performance enhancements, increased frame rate and faster network play. If you have previously downloaded the trial version, you only need to download the patch. To check your version, go to the About box. Multiplayer users must have the same trial version. Users of version 1.0 cannot play with version 1.02 users. Hellbender supports Microsoft DirectX 2.0 graphics APIs, so it works fine with 3dfx cards.
