For one thing, it's difficult to overstate the sheer size of the bug army, and you'll be killing 90% of them single-handedly. The game throws some cannon fodder teammates your way sometimes, and they shoot ineffectually, throw suicidal hand grenades, and repeat the same lines of incidental dialogue ad nauseum. Then they die. They don't run or focus fire, choosing instead to stand and fire while throwing the occasional grenade that may do more damage to them than to the bugs. Your team members, like every other human model in the game, are blocky, blurry, and utterly generic. I counted two, maybe three different character models in the field: the grunt, the occasional fireteam leader, and the even more occasional tech specialist. The bugs are far better defined, but the game puts a lot of them on screen by cutting their animations down to almost nothing, unless they're right in front of you. When you see a rush of them coming down a hill at you (and I saw nothing near the claim on the retail box of 300 bugs at once), they animate with disappointing jerkiness. And there's so damn many of them all the time that it starts to feel like work getting them out of your grill. It ain't Whack-A-Mole, friends. It's more like Whack-A-Million.
