I'm still having problem with "air" related vehicles and missions but thanks for the input.
If i may ask , what do you think about fighting multiple tanks in a city... The idea is to force the players to stay out of some roads and to make them go through windows-filled backyards , to keep them alerts.
Would you like that , or would it be too much hassle to avoid and destroy that much tanks ?
Note : there are a lot of tanks , and you have to destroy them to capture the sector.
