|The new airship pays a visit|
There have been a few graphical changes. For example there's now weather and a cool airship docking regularly at the Command Centre. Game-wise you can now wander further afield while you wait for your mission which keeps the action ticking along.
Other than that I didn't notice anything different, but the game was even more fun this time. I managed to fathom the effects of terrain this time which adds another tactical dimension to the battles. For example hiding in a wood makes you harder to hit but slows you down. I particularly like how being in a crater or up on a rise is handled. Being in a crater absorbs some damage from enemy fire, so get down there when you can. The drawback is that you lose range and visibility. To reflect this the altitude of the camera drops so you have a smaller field of view. Conversely, go up on a hill and the viewpoint moves higher so you can see further and your range increases. The bad news is that you're easier to hit.
