or gain a protective capsule (F) (see Table 1). One fighting aid is given at any one time according to the
number of prize tokens accumulated. Six prize vouchers are shown at the bottom of the screen. There are
three status for each voucher. Firstly, a voucher with a letter informs which weapon is available for activation.

voucher shows that more prize tokens needed to be collected before the particular weapon can be activated
unless the weapon has been activated before.
