How Play in Lan?
- Make sure all players are connected in the lan. This can be done by connecting to the same router, but using an ethernet cable or a windows Hotspot is preferred.
- First player opens "Play 3D" (or play 2D), ticks the checkbox "Network match" on the bottom left, and starts the game.
- Other players open "LAN matches" and click the game of the first player which should show up in the list.
Please see the Getting started Guide for Hamachi, it explains it better than I would. See pg. 14 for installation, pg. 19 for usage.
After all players have joined the same network, just do the steps 2 and 3 I mentioned before.
