The latest Prison Architect update sees some significant additions infiltrating your lovely prisons. Alpha 13 gives prisoners the ability to dig tunnels, giving guards more things to worry about. Introversion's Mark Morris explains that it's a feature that has been ready for a while, but the studio wasn't ready to release it until they had put together a better detection mechanism.
Less noticeable, but arguably more important, is the new punishment table, which gives players the ability to decide how to punish infractions. According to Morris, Prison Architect has focused more on looking after the needs of prisoners, but with the new punishment table, you can rule your prison with an iron fist.
If this all sounds like a good lark to you, Prison Architect is 40 percent off on Steam as part of the weekend deal. Note that it's still an Early Access title, so expect some kinks and frequent updates.
