A full-price package, but you get four titles for your money, and as most of these were once full-price, it's good value.
Elektra Glide is a tricky cross-country racing game with superb graphics and sound effects plus a selection of surreal hazards. Blue Max is Zaxxon, World War one style, as you fly a biplane across diagonally-scrolling occupied territory, bombing and shooting.
Alley Cat originally appeared on Americana and features a feline hero who has to rescue his girlfriend by tackling a number of strange rooms. Colossus Chess 3.0 is just what it says - and it's probably the strongest version of the board game available. All in all, a great collection.
