Quoting Scott Aldridge
Nice, I haven't actually used that unit. Is he any good? :P
Oh yeah, he's good. In fact, he's my favorite hero unit in that game, since he has the best all-around combat capabilities (Lotus & Jarmen Kell are just too specialized for my style). Burton is great for covert missions, especially if you give your enemies a more obvious threat to worry about on the other side of their base. Tired of having your expensive jets shot down by dime-a-dozen rocket troops? Sneak Burton in near the enemy barracks, and he'll show them what a real knife looks like, Crocodile Dundee -style. Frustrated because your enemies hide out in the same annoyingly-placed group of buildings every time you play a particular map? Have Burton leave them some nice “Welcome to the Neighborhood” presents – in the form of remote-detonated C4 charges. He’s just so useful.
