System Defender

System Defender is a Club Penguin game that was launched on January 13, 2011. Currently, all EPF Agents can play this game in the EPF Command Room. System Defender is a Tower Defense type Game. There are also sixteen stamps for this game but at least two more will be added in the future. At least two more levels are supposed to be created soon.



Red Cannon
The Red cannon shoots fast, but weak. It looks like a Gatling cannon, as it shoots fast. It perhaps is a minigun. Costs 50 energy and is best used for the beginning of all levels. (Use 4 before the first wave comes)

Yellow Cannon
Perhaps the most all-round cannon, it has a long range, and as it is a long range weapon, unlike others, its projectiles are unseen, enabling them pinpoint accuracy every hit. They cost 125 energy and are best used for the huge waves.

Purple Cannon
Slow but powerful. Deals a fatal blow to each bot it hits, but shoots slowly. The perfect Anti-boss weapon. Four of them huddled close together can deal death to at least 3-6 boss bots before beginning to leak to other cannons.

Gears
Basically upgrades, but as boss bots already drop them, it is only used in situations where there are nowhere useful to put cannons and/or the bot waves have no boss bots/the boss bots in them don't drop any/little gears. Upgrade to max on one cannon before upgrading another cannon. Can increase range, attack speed, and power.

The leader of all bots. It was also in the Club Penguin: Elite Penguin Force DS game and was rebuilt by Herbert P. Bear. The Ultimate Protobot is also capable of scanning the layout that you have placed, creating attack patterns that will be harder for you.

 * There may be a new DS game following this due to Carrot and it isn't very likely that The Test Bots and the Protobot will get defeated in the LAST level for system defender. or maybe not due to Test Bot Wheel bot has been destroyed in a challenging Field-Op
 * From 2/24/11 - 3/1/11 there was a bug in System Defender, if you click the "Klutzy Level" when the system is not under attack, it would go with the same script and bot patterns as the Ultimate Protobot 10000's level.
