Onyx is a map where hill positions matter for static defense placement and your commander needs to be forward for wreck control. The terrain features hills in the southwest and northeastern corners, which means long-range static defenses like the Gauntlet on those hills can barely reach into the opposing hill area. Knowing where the elevation sits before you place your defenses saves you from building LLTs that cannot hit the enemies you actually need them to hit.
The hill question comes up constantly. A player will ask if building a Gauntlet on one corner hill ranges across to another hill, and the answer is usually that the range barely connects at best. The practical response is to place defenses where they cover your own forward area and rely on mobile units to contest the space between hills.
A strong Onyx habit is pushing your commander forward early to contest the wreck field that forms during initial fights. When units clash in the middle of the map, the wreckage becomes reclaimable metal, and the player whose constructors or commander are closer to that wreck pile pulls ahead in economy.
Running your commander to the forward fight zone serves two purposes. First, the commander adds combat firepower to early engagements. Second, having the commander positioned near incoming wrecks means you can reclaim immediately with the Always Highlighted wreck display turned on in settings. The wreck shows up clearly right in front of you and you grab that metal before the opponent does.
Players who keep their commander safely at the base miss the economy swing from forward reclaim. It is a noticeable resource loss across the length of a match.
One effective Onyx opening follows this sequence:
This opening works well on Onyx because the map rewards the player who can bring the most units to the forward engagement zone quickly. Grunts are cheap, fast to produce with double labs, and effective in the numbers this buildup generates.
Building a second bot lab is a commitment. It diverts commander attention and construction time from economy structures. The question that determines whether this is a good call is simple: can you afford it without starving your first factories of build power?
The answer usually comes down to whether you have those two extra constructors ready to cover the gap. If you build the second lab while your original constructors are still handling all your economy and defense, the lab costs you more than it gives back. Build the constructors first, then the lab, or use the commander to build the lab while constructors maintain normal production.
With hills in the southwest and northeastern corners, static defense placement needs attention to the actual range arcs. A Gauntlet laser tower placed on one hill reaches barely onto the opposite hill terrain. If your goal is to deny the enemy from using the hill positions against you, placing the defense near your own forward area and relying on range to cover the approach is more reliable than trying to hit the far position.
Pair hill defenses with forward commander positioning and a mobile Grunt army, and Onyx becomes a map where your side of the contested zone is well covered while you push into enemy territory with production pressure.
Good Onyx players treat the wreck field as a resource war. Every engagement produces reclaim. The player who reclaims faster gets more metal. More metal means faster unit production. Faster production means the next engagement happens on your terms.
This is why commander forward positioning matters so much. A commander at the fight is both a combat participant and an economy tool. The Always Highlighted wreck setting makes reclaim targeting effortless. You see the metal pile, you reclaim it, you build the next wave of Grunts faster than the opponent can replace their losses.
Learning a specific map opening like this is much more effective when you practice it against players who will give you honest feedback about your timing and positioning. Solo queue games against random opponents rarely teach you the nuances of when the second lab is too greedy or when your commander push went too far. Creed of Champions team games and training sessions create that practice environment where map-specific strategies get tested and refined with experienced players who communicate clearly.
Having a space like here that offers a community, trainings, events, and the guarantee to not be judged or insulted by fellow members is really precious. Keeping the game safe, and more importantly, fun.
Creed of Champions competitive play, zero team-blame. Win with skill, teamwork, and respect.
