Endo Steel Structure is a Mech upgrade that you may purchase for roughly one million c-bills on every Mech (depending on Mech size). It will provide you with a hand full more tons (5% of the total weight) to play with but also occupy many critical slots (the lines where you put your equipment in).

Endo Steel Structure Upgrade

Cost versus gain

Depending on your mech´s size the upgrade will roughly cost one million c-bills. Beware that undoing the upgrade will cost you roughly half that amount again! In addition,you will lose internal space to put items, called critical slots; 14 to be precise. In turn your mech´s structure will weigh only half and thus adding 5% more tonnage to play with. These 5% depend on your Mech size and can be calculated as “Maximum tonnage times .05″. Example: for an Atlas you will have 100 tons and upgrading Endo Steel Structure will yield you 5 additional tons. A Hunchback weighing only 50 tons will get a bonus of 2.5 tons.

Dynamic Structure Slots

How does it work ingame: Dynamic Structure Slots

Once you´ve purchased the Endo Steel Structure upgrade, you will notice two new kinds of items appearing in your critical slots (the lines where you equip your stuff): Dynamic Structure Slot and Structure Slot. These mark the places where the Endo Steel Structure resides within your Mech. However, they can be automatically moved to a certain extent: Dynamic Structure Slots can be treated like free slots. The Structure will be moved to another part of your Mech (where ever some space is left), and you can mount your items in Dynamic Structure Slots like in any other free slot.

Once you no longer see Dynamic Structure Slots you are out of space. If you are out of space and still have some tons left, I´d recommend maxing out armor and see if you can upgrade a weapon to something heavier without using up (much) more space e.g. Medium Laser to Medium Pulse Laser.

When to purchase Endo Steel Structure

The following list will give you a rough idea on when to consider Endo Steel and when you should think of something else. However, certain situations and builds may contradict these guidelines.

• Endo Steel Structure is  highly recommended on light and medium Mechs. Heavys often times but normally never a good idea on Assaults.
• If you need more heat sinks and/or more ammunition do not go for Endo Steel, but consider upgrading to Double Heat Sinks.
• If you are planning not to put much/anything in your arms go for Endo Steel Upgrade.
• The smaller/lighter your Mech the higher the chance Endo Steel is worth a look.
• If your Mech runs with a lot of lasers, stream srm2 and other small weapons with little/no ammo Endo Steel Structure is worth a look, too.
