In Harpoon Lagoon you're a fisherman who's got a quota of fish to catch. If you don't catch enough fish to hit your number, the game is over. However you can rack up some serious bucks if you are a good shot with the harpoon and then you can buy fishing upgrades like better fuel for your boat, a bigger motor, good fish bait and more. Each level gets more difficult and you have to catch more fish to continue so you need to be fast and accurate, because the clock is ticking. This is a great addition to our other fishing games which include shark fishing, river fishing and lake fishing.
