GGN Reboot/KŁA has won every game compo held at Sommarhack so far. That includes Crackman, Super Cobra, River Raid and Joust. GGN admitted he's not very good
at neither Obsession or Dropzone, so there is hope!
Atari XL/XE game competition
DROPZONE, a classic by Archer Maclean, released in 1984 on the Atari XL. It's Macleans first released title and received good critics back in the day.
Shortly put, a smooth shooter using the Atair XL hardware nicely.
