Why no Episode 3 ???

[Googolplex]

No other horror-game is better than PENUMBRA, because the other games don't have a good story or they have too much action and no puzzles.
The dark corridors are better than all other bloody zombies in other games.
And the best is, you only have hammer or pickaxe - or no weapon.

Why no Episode 3 ???

Frictional Games now works on an other game, but an other developer can make Episode 3. Paradox Interactive only have to organize it. When the rights of PENUMBRA are by Paradox Interactive, then they can search for an other developer.

I think that's not impossible.
