It's a good thing that this game is free to play. If I had paid for it, I'd be pissed.
My biggest complaint is that enemies spawn instantaneously/randomly. I played several rounds in practice mode and did reasonably well. Enemies light up on the HUD, you can see them dropping in, even at a distance. They appear/disappear on the HUD.
Then I went into the regular battle royale and it is totally different. At levels 1-10 I was playing against L50+ players and quite often against L100+. I have played other FPS games that populate the rosters with players of similar levels, within a reasonable range, sometimes with a few high level players, but usually players +/-5 levels, so it's not a total slaughter fest.
The enemy indicator will show 100+ enemies, but no red dots on the HUD. In many rounds, I've maneuvered from one quadrant to another without ever spotting an enemy, often crossing open fields, sometimes maneuvering under cover, without encountering any enemies. Then, out of nowhere, an enemy spontaneously spawns and kills me, often from a spot that I just walked by. Or after entering an empty room, an enemy appears to kill me.
After three days, I deleted the game.
