H1Z1: King of the Kill vs Horizon Source
H1Z1: King of the Kill
H1Z1: King of the Kill is a competitive, battle royale-styled MMOTPS game set in a post-apocalyptic world where everyone's fair game as you scavenge for supplies and materials to gain the upper hand. Gameplay-wise, the game is pretty fast-paced and intense especially when the map shrunk to a relatively small area, but of course, to be a pro, you'll need to put in the effort and the commitment to improve. Newcomers might find the skill ceiling a bit high though so you can expect to be fodder for quite sometime until you are familiar with the few maps available and know which stuff are hazards and which aren't.The shooting mechanics in this game is pretty arcade-like I suppose - it's the hit-or-miss type without the chance of getting glancing blows, and there might be a few weapons that might need adjusting - shotguns for example - but it's still okay overall. However, if you are to compare this game with another battle royale game like PlayerUnknown's Battlegrounds (PUBG), you'll find this game seriously lacking.
So, if you've got the cash to buy either H1Z1: King of the Kill or PUBG, we'd actually recommend getting PUBG since the game has a ton of players right now and you won't need to wait too long to get into a game. Not to mention, PUBG does have a lot of stuff that's better than H1Z1. But if you like having lots of skins or if you have a lower end PC, then H1Z1: King of the Kill might be your best bet.
Horizon Source
Horizon Source is a battle royale game that many have dubbed as being the ultimate blend of PUBG, Fortnite and Overwatch... though graphics-wise, Fortnite is definitely the major influence. Similar to most games in the genre, you'll be dropped into a map where you'll then battle against other players in hopes of ending up being the last man standing. You can also build structures much like in Fortnite and resources are pretty much plentiful in the game. The gameplay feels a lot better as well - expect to be rewarded with more kills for having a good aim.However, unlike the others, this game only has a 4-man team-based game mode so you can't really play the game solo as of yet. There are other game modes as well, including a zombie mode, but these aren't ready so far. Interestingly, the game also gives you the option of playing in first or third person view. Naturally, playing in third-person can be more advantageous to you since you can see your surroundings better. There are no drivable vehicles in this game though.
Despite the many random bugs, lack of an EU server, some character balancing issue, and broken English, Horizon Source seems to be a real contender on PC against established battle royale titles like PUBG and Fortnite. The game can be incredibly addictive and fun to play. So, if you enjoy playing battle royale games, Horizon Source is a game you'll want to try!
