I bought Harrier Attack for £5.95 from Tesco back in 1983. That was an incredible sum to me back then, but I'm glad to say that I got my enjoyment from it. I thought it was ever so naughty at the time.
There has been a good article about Durell software in Retro Gamer issue 11, if you can afford to buy a back issue off EBay. To my great joy they are still out there, though now peddling insurance software.
I still contend that Durell is the best software house for the Spectrum. I've got my mind to do Turbo Esprit or Thanatoss in the future.
Durell solutions - They are still going in Taunton. Yay!
