I have played your map. It is very good but it needs some work to do.
-Try improve your map environment more
---Less Vegetation on the 'cold earth',
---add more winter particle and add snow wind particle to give good cold and realistic feel to the level
---Do a little work on mountains, terrain - I can see some triangles and sharp edges on terrain
---Use voxels more, Voxels are best tool if you know how to use em like me.
---Add more point of interest in the maps - such as buildings, abandoned car, old crashed aircraft
---Try think snow, try lower the road lower than normal to make it like a compacted snow road.
-dialogs, objectives, goals, mission
---#To tell you truth, those things are confusing sometimes
---try add header name to every dialogs like this
COLONEL JACKSON: What do you need Nomad? ... You need Warhead??
---Try cut the LONG messages (ones in the beginning) into two messages or more. The ends of the message will get cut up in edge of screen.
---Add more waypoints (objective point) While playing the level, I was worried about going to wrong way a lot when I noticed the objective waypoint was on my left and I'm following the road forward.
---Don't use infomessage for objective direction like when you was trying to get over the wall, you will prompted to use O for reinforcement. It is better to move that message to HUD Message since its a hint or prompt not communication.
---Bugs on trigger detection like aircraft carrier, you get on VTOL. Then you get transported to the space. I got there without a VTOL :S
---Try use VisAreas more on human buildings
---Try fix the big black line when you enter the tunnel from the research place.
---Little lot spelling errors :S
---The gameplay is little bland. Try invent more challenges, detours, etc.
That's all. Great map, it will get better if you work on it more.
