We are stuck on the base line again, with six different waves of unfriendly freaks to see off. Our triple-steamed laser gushes out continuously, if desired, mopping up all comers till the enery cells are drained: then it's down to dodging about as they recharge.

Anticipation and timing are therefore essential to get through to the bonus screen. This entails a testing journey through a tricky space lane (it looks suspiciously like a road) gaining an extra ship at the end. It hardly need stating that the tempo hots up as we face the various nasties again.

The laser rays make an exciting graphic display but more imaginative use of colour would have made the aliens more spectacular. The sonics are from the standard recipe book and as such are ok. Verdict? Really should be worth translating for the C64!
