Hint: Extra Target Tip

While traversing the various Space Battle levels, you may be mystified as to what the “Extra Targets” are that are mentioned at the end of each level. For instance, at the end of a level, you might be told that three of five “Extra Targets” were “Destroyed”. Since you get Gold Bolts for destroying these targets, you’ll want to be able to readily identify if one has been destroyed or not. That’s easy enough to do, since each enemy destroyed who is considered one of these targets of interest will give off a multicolored glow when obliterated.

Hint: Upgrading Raritanium

Customizing and upgrading your weapons can be done in any number of ways. To increase the amount of Raritanium you acquire immediately, however, try upgrading your weapons initially in terms of their Raritanium output when used. Since many enemies give up Raritanium when killed, you can make them drop more by using weapons upgraded to increase Raritanium output. Upgrade the output before upgrading anything else, and you’ll have plenty with which to upgrade before long!
