Destroy Objects to Uncover Goods

Around each single-player map, you'll find dozens of barrels, boxes, and other debris just waiting to be destroyed. Particularly if you need energy or shield units, fire some simple lasers at the objects to destroy them. Occasionally, you'll uncover energy and shield power-ups from the boxes or barrels. Because they explode, however, don't situate yourself too close when you fire off a few rounds. And, since these are harmless boxes, don't waste useful ammo or missiles blowing apart a nonthreatening piece of metal.

Sometimes you'll run across boxes or barrels that have other special properties. For instance, a reddish box blows up much like a frag missile. Get too close to that fiery explosion, and you'll find your shield units diminishing rapidly. Also, a yellow-topped barrel contains napalm and will cause fire when it explodes. Sometimes, you'll discover these planted above rooms or ledges. Use the barrel to your advantage. If several enemy bots are scampering below, blow apart the barrel and release the destructive napalm (it falls according to gravity). If any bots are floating around underneath, they could be lit up quickly. Also, lure bots next to barrels or explosive boxes and use them to your advantage. It's a tough technique to pull off on a regular basis, but it's one that could turn the tide in a battle where you're clearly overmatched.

Frequently, when you destroy an enemy bot, you'll find shield or energy power-ups floating in the debris. Don't overlook them; grab them if you need them. You can't take unused shield or energy power-ups with you to the next level unless you snag them! But, because you can only hold 200 units of each, don't necessarily grab a power-up if you are sitting on 198. Wait until you fire off some shots or take a few hits, then return to the area and grab the goodie.
