Today i started the construction of a High Security Prison complex, Thanks to the army mod for the Barbwire and Chainlink fence wich gave me the idea. Escaping from this prison is not easy, you wil have to kill another inmate to obtain items (thanks to badplayer mod) in order to be able to escape, in combination with the better HUD and Hunger Mod not trying to escape wil result in death by starvation (wich would be nice on survival server). Instead of wood poles i used Bedrock bars to connect the chainlink fences wich worked out realy nice, and most of the floor is made out of unbreakable concrete and some normal stone, however whole the place has protection so forget about just breaking blocks..and theres a huge forest around the whole prison where loads of monsters hide and spawn.
FYI : (For Your Inspiration)

Im building this prison in Creative mode.
A screenshot in daylight, soon more buildings and areas wil be added to the prison (in other words it gets expanded).

However here´s a Home im building in Survival mode on Remarco´s minetest server :

And here is a image of a Complex im building in creative that takes you back to the days DOOM95 came out and when we played games like QuakeII with terrible graphics on a Windows98 box, walking trough the levels for days searching for keys and clues only to find out your back where you started as soon your close to completing the level.. All images i share from structures i build are in early stages and wil look much better in near future..

Hopefully you like my work and it gives you ideas and inspiration to play and build cool stuff too ;-)
