The AI <a href="http://www.fut15mall.com/">Fut 15 Coins</a> can offer occasional challenges, particularly in levels featuring intersecting corridors in which human enemies will flank you, use cover effectively, and tumble to the side should they find themselves gazing down the barrel of your automatic shotgun. They will also tip over furniture or other objects and use them as cover (a trick you can use, though will likely never need). However, enemy behavior is inconsistent; a table-tipping guard may not follow through, running away from his improvised cover rather than ducking behind it. Some enemies will blindly fire from behind low obstacles but may also do so when in plain view. The best adversaries are those not governed by rules of human behavior, such as ethereal foes that take shape as you enter reflex time. And in some cases, your enemies are so visually elusive that you're better off finding a way out of the dark environs that spawn them.
The most notable additions to the formula are a couple of armored-suit sequences in which you climb into a giant metal mech and riddle your attackers with machine-gun spray and rockets. These sequences aren't tough--you're a powerful death machine plowing down your weakling foes--but the mech controls nicely and you'll be treated to some impressive displays of environmental destruction and general chaos. You can move through these areas on foot if you like, so these levels do offer a bit of replay value, though you should take great pains to wreak fun robotic havoc when given the possibility. You'll also take control of the turret atop the squad's armored vehicle, but this weapon isn't all that enjoyable to use, and these bits feel like filler.
