The Dead Awaken - an online web-browser based game that my son turned me on to. While not the best of games, it does have a strange addictive quality to it. Fortunately for the user, it is turn-based and you're only given a full set of turns each day. While you can earn extra turns, the site is probably best visited at most three times per day if you want to use all of your turns.
On the site, I play a zombie - but it's your choice, human or zombie. You can visit the graveyard and go grave-robbing, head down to the mall to kill some wandering zombies/humans, or even head down to the subway for a mission of smearing blood on things to attract more zombies (and get paid for it).
The game harkens back to the like of the old BBS games we played and wrote back in the 1980's. Trying to become top zombie will probably take you awhile, though. The game rewards those who've played the longest, so I'll probably never hit the Top 10 lists on this site.
It's an interesting diversion, and very different from the MUD experience. Give it a whirl and let me know if you like it.
