A small covenant map known for its symmetry and few weapon spawns, Zealot, contains only one power weapon; the sword. Here is an image I've uploaded from within the game and edited to contain the newly updated weapon locations. It's a top view of the map containing a red and blue dot showing where both teams initially spawn.

The Power Weapon
Unlike most maps, Zealot only has one power weapon and it doesn't even spawn at the start of the match. The sword spawns in the top middle of the map exactly two minutes into the game. Most people usually forget about the sword or get caught up somewhere else, so it's an easy grab if you wait for it. Normally I recommend using sprint in just about every map, but jet pack is equally effective in Zealot, if not more effective due the fact that there are three levels and no power weapons at the start.
Keys to Success
Top map control and team work are both crucial in this map, and when I say "top map" in Zealot, I'm not referring to the outer location that's accessed via gravity lift or jet pack known as "space". Top map is the floor where both teams originally spawn. Since there are almost no power weapons, Zealot usually becomes a DMR battle between both teams, so remember to pace your shots and help your teammates like always.
In Zealot there really is no perfect setup since it's such a small map, but if there was, it would be to always take control of top map. If your team is spread out evenly throughout the top of the map, the opposing team should always spawn on the bottom floor right under you giving your team the advantage.
