The Last Shelter
In Tofee Games' new stylish and challenging addition to the tower defense genre, The Last Shelter, a habitable planet has been found after years of searching and it's time to put down roots and start building energy collectors. But there's a catch, as there so often is in sci-fi-themed tower defense games: you are not alone. You'll have to battle it out against spiders, scorpions, armored beetles, and all manner of creepy crawlies if you are going to survive.
In each stage, you start out with a small amount of energy and a limited choice of where to place three different kinds of guns... weak, but rapid firing blasters (100 energy), slow but powerful heavy guns (150 energy), and devastating but expensive rocket launchers (250 energy), all of which can be upgraded as you progress through each stage, and more upgrades are unlocked. The challenge comes in gun placement. You can only place turrets in spots that have access to thermal energy, which amounts to only a small fraction of the map. Do you place the heavy weapons closer to the base, or nearer to the energy collector?
If things get real tough (and they will), you have the ability to call in air support, in the form of conventional bombs or nukes. But use them wisely, because you will have a long recharge time before they become available again. If you do manage to beat back the relentless insectoid onslaught, you will be rewarded with experience points to go towards upgrading your turret armor, reload times, resell value, as well as valuable enhancements to your bombs and nukes.
The most frustrating, and unique, thing about The Last Shelter is its sheer challenge. Even on Easy it can seem close to impossible to beat. And, while it could have clearly benefited from more turret choices and upgrade paths, it does push the limits of both casual and flash gaming in creating a stylish and professionally made free game that will have you playing and strategizing for days beyond that initial lunch break session.
