Many interesting things can be found by digging around the net.
One that's recently come to light is the Zombi horror survival game Urban dead. this is an online text rpg set in an abandoned and quarantined city, where you can choose to play either as a surviver, trying to rebuild your shattered life, or a zombi, trying to snack on as much living flesh as possible.
the game is highly accessible to screen readers and has a very active player base and fan community, and extensive gameplay info is available to new players. You can find the Urban dead game by lirching onto this link.
But if gamebooks are more your thing, there's no need to miss out on the terror, sinse a new title has been added to the Whitestick.co.uk fantasy gamebooks page, Mansion of Maleficence. In this short adventure you will enter an extremely unpleasant house, teeming with ghoolish creatures and grizly fates for you to stumble into, even for gamebook veterans, this one is a challenge.

Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
