if you owned a Sega Saturn back in the day, Death Tank Zwei and Death Tank were the greatest games you never played. You could not buy these games, they were hidden unlockables, buried within the games that housed them. There were only a couple of ways that these games could see the light of day:
a.) The original Death Tank can be unlocked after obtaining all 23 Team Dolls in PowerSlave.
b.) Death Tank Zwei can be unlocked in two ways: 1. Destroy every toilet in Duke Nukem 3D(including the secret level, Urea 51), or 2. Have a Quake saved game on your system
Once you unlocked it you had a rare treasure of a multi-player game. Rare no longer as the DT will rise again in the XBLA space. If you want to read more on DT, just click the link below and you will be up to date. No launch date or prices have been announced at this time.
Take it from me, this game is worth checking out. Think of it as a fast-paced worms, all in real time. And wit 8 player online support, who knows what kind of carnage will erupt!
