3. Contract Killer
IAP: Nanotech Sniper (~$100)
Armed with nothing but a hunting rifle, the titular character in Contract Killer makes a living killing people he’s hired to snuff out. This freemium game is mission-based, and each contract you accept requires to scan the crowds in its 3D environments for your targets and take them down. Seems simple enough, but it wouldn't be a freemium game without some sort of catch. Each time you take a shot, whether you hit your target or not, you lose ammo and either have to wait for it to refill or purchase replacement packs. You also can’t just take as many contracts as you want, so you’ll need to wait a while before new ones are available. Of course, dish out some cash and all of these problems just go away.
In-app purchases eliminate the need to wait, and you can even buy contracts if you want to play right away. Guns, however, are the best investment you could make as they increase your accuracy and reduce the need to get more bullets. The game’s best weapon—the Nanotech Sniper—comes with unlimited clips and provides you with the perfect shot every time. This contract killer’s best friend can be yours for just 2,300 in-game credits (that’s about $100 right there). Patience is a virtue and it can save you a whole lot of money too.
