Gears Tactics
Not your normal Gears game, instead of a cover mechanism, this time Microsoft went for a turn based mechanic like Xcom.
UI
The menu UI takes a bit getting used to, you select a weapon type and then enter that mode
Grenades
On a few occasions I healed a bunch of Grubs
Combat is fantastic! In one encounter, a Grenadier vaulted over a wall, kicked by character away from the wall, pulled his shotgun and downed my soldier. That is some seriously good Behaviour Trees!
