The PortalGuns can be used to pick up blocks from the ground and move them to be placed somewhere else. Two portals can be placed and used to walk through to get teleported from one point to another. The PortalGun Wood & Stone is used to place the portals. The gameplay elements include features like the PortalGuns to place portals, a GravityGun which can be used for both blocks and mobs and lots of other nifty tools.
Portal 2 Mod (previously Portal Gun)adds many of the features as found in the popular first-person puzzle-platform Portal games.
