IGN has a complete guide to the single player campaign mode. Sure, you can be "revived" by your squadmates, but what happens when you're all alone on a Separatist Core ship and facing by twenty Super Battle Droids? Don't hesitate, get our campaign strategy guide today!

• Learn! ... the subtle nuances of squad command. Not all orders are the same; some endanger your squad in some cases, while others are often overlooked in the heat of battle.
• See! ... what's on the other side of some very crucial doors. Unless you don't mind re-loading your game every five steps, you might want to know when to breach and when to slice a particular door.
• Find! ... the best weapons. Alien weapons are everywhere. But get the best ones for the mission at hand, or expect to fight off spider and assassin droids with vibro-weapons.
• Escape! ... the cunningly planned ambushes Lucasarts designed to kill you. Sometimes death scenes are cool, but when you're the star of these gory skits, the fun factor drops. IGN will help you outwit the game's designers and avoid their heinously planted traps.

Want to shock a droid for free? If you have a concussion rifle on hand, use its melee strike to stop and drop a droid in hand-to-hand combat. The shocking effect on droids is the same as if an electronic detonator was used.
