Played a few hours last night (single player, "Recruit" difficulty), and I'm liking this game.
Surprisingly, controlling your teammate with the d-pad has been pretty intuitive:
- left: re-group
- up: advance
- right: hold position
one click puts him in a "passive" version of the order, while two clicks have them do an "aggressive" version of the order. I've been using the orders to have us leapfrop from cover to cover, or have my teammate go all aggro on the enemy while I flank (or I go all aggo and have my teammate advance up under cover for the kill).
When I get incapacitated, I haven't had any weird hiccups with him coming over to help - only time was when we were getting overrun by the enemy on a rooftop while he was dragging me and it resulted in our deaths (he was getting shot repeated and was kinda flipping between dragging and shooting back).
Not sure if it will be the harder levels that will tax and AI, but I'm looking to seeing how it turns out.
Plus, the teammate AI has been doing it's part in the battle, and the kill count hasn't been too lopsided.
The only odd thing I've seen is when you enter "Overkill" mode - my AI partner rushes ahead quickly and somehow manages to kill everyone ahead of me before I get there

. However, being too lazy to read the instructions so far, perhaps Overkill works like that?
Otherwise, haven't used the dual sniper mode too much, and the back to back is almost like a mini-game on how many enemies you can kill before getting kicked back into realtime. I've enjoyed being the shield bearer.
Overall, you can kinda say that AoT comes off as a less polished Gears of War, but the modern setting plus the customizable weapons (plus the concentration of mechanics on you and one teammate) has made it feel - to me - more fun to play. I generally play single player games, and I was hesitent this game would just be me babysitting the AI, but it does kinda feel like you're fighting in a team. Looking forward to playing it co-op.
Current load-out preference:
Primary: heavily modded HK 36 with shield (no undercarraige weapons to maintain accuracy)
Secondary: plain P90
Special: tried the RPG, but will go back to a plain M14 sniper rifle
Saving up for a SAW to go nuts with aggro
