UFO Aftershock is the second of the three and in my opion the best of them. Aftershock follows on after the first, the Biomass has taken over and colonies of mutants are appearing, both friendly and unfriendly. Aftershock follows more of a story line with side missions of helping other fractions for rewards such as territory and favour.
The weaponry is far larger than Aftermath, bringing in alien weapons to begin with, to then creating various human weapons, to stronger energy weapons. Each of the human weapons can have customisations such as stabalisers, scopes and muzzles to improve them further.
Soldiers can be trained still, but furthermore the player now has input into what stats are enhanced, meaning that if you want to create a squad of Snipers, you're not waiting for the right soldiers to come by with the right traits, but with the investment of time can make them yourself. This offer a great deal more personalisation to squad development.
Two new troop types have been added aswell appearing as Psionics with telepathic abilities and the Cyborgs who can manipulate inplants that enhance stats.
Combat is a lot easier, however when moving troops during live play, can often lead to difficulties as the actions switch to any character whose finished an order, or pausing for various reasons. This is a decent RTS that rivals most recent releases and for a game nearly 10 years old, it has fantastic playability and easily 60-100 hours of gameplay.
The full screen issue I would say is not a problem. I play on a 22" and have some small black lines down each side, but it doesnt take anything away from the game. There are fixes and patches on the news link where the developer of fix has commented for anyone who needs really wants full screen.
Check out my video below for the first 15 minutes of play which show you a number the features discussed above.https://www.youtube.com/watch?v=HvPGWLqKo6A
