Great looking games above and no doubt many more to follow...
Played Xenos Rampant at the local club. Had a fun game.
Though the elite infantry don't make much sense, unarmed cheaper aliens proved a much better option. Would have liked longer-ranged weapons and the vehicles in this case two large mechs seemed a tad underpowered.
Looks like you had fun and the terrain and models look great.
We found the Elite Troops very effective, especially when in cover - almost impossible to shift) and the Walker (Deff Dread) seemed powerful. But it's early days and all quite situational - no doubt we'll work out counter tactics and how to exploit weaknesses!
Bit puzzled by the "longer ranged weapons" comment - apart from weapons with only 12" range (which represents pistols and side arms) everything else can shoot any range they like. Their targets get a +1 to armour once they go over the base range, but (LOS permitting) you can shoot anything you can see on the table.
