Same problem as the "Why2K?" achievement.
For this achievement you are supposed to score 4,096 points in Score Attack mode, but when I was going for this, no matter how many points I got in a round, it wouldn't give me progress towards the achievement. For me, the only thing that worked was completing a round. So, I think the achievement is not for scoring 4,096 points, but for completing 4,096 games.If you have completed "Why2K?" you will have 48% progress towards this

Select "Asteroid X" > ClassicAI kills count towards your progress.
The game ends as soon as someone gets a kill, which usually takes about 10 seconds. You'll get about 6% progress per hour.Method 2:Hairy Cabbage
pointed out that you can also load up Zones, set it to 10 points with 1 AI and the game will end in less than 10 seconds almost every time.
