3 Commando Brigade

i44 maps

The plus is the historic context, but in-game they are very A2.

Few buildings are enterable, and not the same level of detail we see in the newer A3 maps.  Good for armour, not so for infantry.  

Also quite a few script errors.

A real shame

I have no experience of map making, but since there is only maybe 2-3 people in the whole BI community that can make good maps, I suspect its bloody difficult and extremely time consuming.

EDIT.  Years rather than months.

EDIT2:  Look up the XCam tool

My understanding is that it isn't terribly complicated for the most part (with a few notable exceptions), but that it's just a vast amount of work in terms of actually forming the terrain from whatever basis you start from, defining the materials throughout, and then populating the map etc. For funsies, have a guess how many trees are in Chernarus...

I know there are some good resources out there explaining map making, try taking a look at these:

Take a look at the XCam tool, it might reduce the coding required

Xcam streamlines the populating process, so you've already formed the basic landscape. A few maps have been made with Xcam (such as Taunus, I believe?).

Yep, Tannus was made as a demonstration of Xcam
