Alien Grounds is 84% off during the Steam Summer Sale.
The June Challenge is also entering its last stretch. The leaderboard now has 25 scores, and the current leader is ahead with 16,443 points.
If you already own the game, this is a good time to jump back in and try to improve your score. If you do not own it yet, the Summer Sale discount makes this a great time to join.
