Good old Alternative - and there's a name you'll see quite a bit this month as they've just deluged me with an enormous parcel full of the budget goodies and other games that they're slipping out on the quiet.
Most impressive is this reissue of the Incentive conversion of coin-op classic Moon Cresta. Remembered chiefly (if at all) for its crazy, and virtually unworkable Lenslock security system, this is fairly standard space shoot-'em-up seen in a hundred versions from Superior's Star Striker onward.
This is the one where your three part spaceship has to shoot all the aliens twice to destroy them and where the only breather you get is the docking practice between levels.
Nothing outstanding here but superb value for the money and it is great to see classics being prized out of back catalogues to entertain us again.
