Items can be equipped on a mech. It's not difficult to obtain items. They're dropped most commonly by bosses, but that doesn't mean normal enemies don't drop items; therefore one should, ideally, try to kill as many enemies as you can. Each mech can equip 1 to 4 items depending on the mech. Generally, more powerful mechs get less equipment slots, but this is not ALWAYS so. You can only get a maximum of 9 of each item. It is generally recommended to equip items, it can make things much easier. Since there are no visual aids, there are listed the Japanese names of the item too, so it is easier to understand.
