"It’s been another massive month, with several major successes. This month we tackled one of our big end game features : prisoner reform. You can now run prisoner reform programs which aim to train, educate and reform your inmates. Reform programs are expensive to run, take a long time to complete, and the success rates are often very low unless your prisoners are very well taken care of. Some bring substantial benefits to your prison and the inmates that take part, others are a longer term investment in your prisoners that may provide little short term benefit.

We have continued to expand the armoury originally introduced in alpha 17. You can now unlock tazers for your armed guards, and eventually issue them to all the guards and dog handlers in your prison. These are non lethal weapons that instantly incapacitate a prisoner without causing any damage, however they can only be fired once before needing a full hour to recharge. Perfect when a prisoner is smashing up his cell, not so great when outnumbered in a riot. We have also added new stab vests to the armoury, which give your guards extra protection in a fight, but slow down their movement as well.

Prison Architect is trimming up to be one of the more elaborate and fun sim games i've played in quite some time. I really enjoy how they add to the feature pool of the game for very specific reasons that don't detract from the overall game itself.
