Whether by some miracle you have greatly reduced in size on Zarium, or whether some giant mutant bugs have invaded the planet, now is not the time to find out! Those oversized arthropods aren't looking at you kindly.
Who are you, I don't know you!
Not only do you have to deal with cockroaches at home, but some monster bugs showed up here, too. Good thing you brought a 10-shot gun, which is quite helpful in subduing the attacks of the overgrown ants. You can't defeat the beetle with one shot, so three long-range hits and the creepy beast goes to sleep.
Sad news: ammo tends to run out. The good news is that the R key helps you reload your weapon. See if you can hold out until help arrives among the hordes of these mega-locusts!
