Titanfall has Frontier Defense. It gives you turrets to place.
And it's the best thing ever. EVER. (Done by Respawn.) Can always seem to find a game on PC at least. It also shows the flaw of limiting the number of other players so low in the standard Attrition mode because having whole waves of Mortar and Nuke Titans to battle at once is crazy yo.
Its maps aren't really that small either...especially vertically.
EDIT: Paid like $10 for Titanfall and then $5 for Season Pass (which they then gave to everyone for free like a month later but I ain't too mad) and am like Level 49 or somethin with basically everything unlocked and my playtime is like 90% FD, 5% Attrition, 5% Domination. I give it a 9.75. AW gets a 9.5.

My five score scale is 9, 9.25, 9.5, 9.75, 10.
