Yellow Armor absorbs 60% damage and provides 150 Armor points.
Players in Yellow Armor cannot collect Green Armor unless their Armor points are below 50.
- In single player, the Yellow Armor is somewhat common in maps and is usually found in the open in Episode 1: Dimension of the Doomed and Episode 2: The Realm of Black Magic. In Episode 3: The Netherworld and Episode 4: The Elder World, on the other hand, it is usually reserved for secrets. Since Red Armor is very rare in single player, you'll find that Yellow Armor is a great protection against your foes.
- A player with both Yellow Armor and 100 Health can absorb more damage than a player that has Red Armor alone. While this can be difficult to pull off, such a combination can turn the tides of a battle in your favor.
- A room that has Yellow Armor is usually a major control point in a map, given how powerful it is. As soon as a match starts, some players tend to rush the YA room so that they can grab it. If you get in control of it, DO NOT let go of it! If you control the YA room as long as possible, you'll get a lot of frags and be able to deny enemies from using it. If you do lose control of it, try to get back in ASAP and regain control while the others are fighting to see who will control the YA room.
