System Defender

When starting System Defender, you have lots to choose from. You can play Tutorialmode, Advanced mode, or the Defend System mode. Please take note that the Defend System mode is members only.

OBJECTIVE

The object of the game is to stop the robots from attacking the system. To prevent the robots from attacking, we use our cannons. There are three types of cannons.

The Red CannonCost: 50 energy.
Speed: Fast
Damage: Low

The Yellow CannonCost: 125 energy.
Speed: Medium
Damage: Medium

The Purple CannonCost: 200 energy.
Speed: Slow
Damage: High

HOW TO USE A CANNON

To use a cannon, simply click on it and drag it on to the battlefield. Keep in mind that you can only place the cannons on to the highlighted blue circles. If placed correctly, the square in the middle of the radar should turn green.

However, if you do not place your cannon on to one of these blue highlighted circles, the square will turn red.

GEAR

Now, let’s talk about the gear. Gears can be obtained in different ways. If you defeat a boss bot, it could drop a gear. Another way to obtain a gear is to buy it. A gear costs 500 energy.

The GearCost: 500 energy.
Speed: N/A
Damage: N/A

What’s a gear? The gear is used to upgrade your current weapons. If you take the gear, and drag it on to one of your cannons, it will make it stronger. Take in note that you can only upgrade a cannon twice. Let’s take a look at the yellow cannon for example.

Here’s what the yellow cannon looks like with no gear attachments:

Here’s what the yellow cannon looks like with one gear attached:

Here’s what the yellow cannon looks like with two gears attached:

Gears are a key element to winning in System Defender and it is recommended that you upgrade atleast one of your cannons with them per game.

STRATEGIES

Now, let’s teach you some strategies. You will ALWAYS see the robots on your radar before they actually appear on the battlefield. You start off with 200 energy. It is recommended to buy four red cannons, and place them at the very start (where the robots come in to the battlefield). Kind of like this:

This way you can take out all of the easy enemies, gaining more energy for the hard enemies. It’s key that you use the energy you earned from taking out the easy enemies to buy yellow cannons, and place them at the end near the system. This way, if enemies make their way passed your red cannons, they’ll be easily taken out by the yellow cannon.

You should try to fill out the entire battlefield with cannons. What I mean by this is you should fill every single blue circle. This way, it’s nearly impossible (even for a boss) to make its way to the end.

STAMPS

There are 10 stamps for the game System Defender. Here is a little description of all of them:

1. READY FOR DUTY

This one is fairly easy, probably the easiest of all. Just go into the Tutorial mode and finish it.

2. GARBAGE DISPOSAL

For this stamp, you need to go into Advanced mode. Once there, click the first level and destroy 100 enemies. Pretty simple.

3. BUG OVERLOAD

Both non-members and members can complete this stamp. Basically, go into either Level 1 or Level 5 and defeat all of the rogue bug robots.

4. STRATEGIC SUCCESS

This one is easy if you’re experience with the game. You must destroy 100 enemies WITHOUT using a gear upgrade.

5. UNIGUNNER

For this one, you must complete a game with only ONE type of cannon. Although the red cannon does the least damage, it’s recommended.

6. TACTICAL PRO

This one is a challenge. You need to destroy 100 enemies without getting one scratch on to your system! Level 1 is highly recommended.

7. MASTER MECHANIC

To complete and earn this stamp, you need to fill every single socket (blue circle) with a cannon. Level 1 is recommended.

8. STRATEGIC MASTER

This one’s a bit harder than the one we mentioned earlier, you need to destroy 250 enemies without upgrading a single cannon.

9. TACTICAL ACE

This is a tough one. You must destroy 250 enemies without one of them getting into your system. You cannot earn this stamp on Level 1 as there is not enough enemies. Stamp must be earned in Level 5.

10. PROTOBOT ATTACK (members only)

You must protect the EPF mainframe from the Ultimate Protobot. This one is tough. You need to enter the members only mode (Defend System), and beat it.
