Konami‘s 1982 arcade game Tutankham is a weird horizontally-scrolling shooter where you play a gun-toting archaeologist, fighting off snakes, mummies, and other meanies, inside a maze-like Egyptian tomb.
The ‘rub’ is: that you can only shoot horizontally, and not up or down tunnels, which makes moving around the tomb difficult. Monsters appear from ‘generators’ and come thick and fast – too fast, to be honest. Getting past certain places is almost impossible and requires more luck than judgement. Like many early arcade games…
Tutankham could have been a great arcade game, but its difficulty lets it down, in my humble opinion. It’s still an interesting game, and a decent challenge, though.
