Contract Killer 2 tasks you with killing specific targets, henchmen, and other enemies in an on-rails style shooter with a number of unique elements. The game is incredibly violent as one might guess from its name but it runs smoothly and has a number of options for those that enjoy similar stealth and ranged combat-style games for consoles.
Contract Killer 2 takes some time to install, loading numerous components when you first turn it on and generally slowing down between levels, cut scenes, and menus. It can be frustrating, at times, but the game, itself, runs smoothly and without a lot of choppiness or slowdown, so you won't notice it as much after the first time you open the app. The game shows you what to do in a quick but thorough set of tutorials and afterwards it opens up a bit, allowing you to take out enemies in a number of ways from both close up and far away. The rail-style combat is interesting and requires you to think about which angles are best and where to move as you progress through a level, but it does feel a bit stale in some levels because of the lack of options.
Contract Killer 2 is not quite fast paced, but it never slows up, either. The free version lets you play most of the game and unlock new abilities and levels as you move your way through new contracts. There are upgrades to be made if you like it and want to use everything in the game, but for a quick distraction it is a decently fun game.
