Horizon Source vs Still Alive: Survival PvP
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!
Still Alive: Survival PvP
Still Alive: Survival PvP is more of a competitive arena shooter with survival and crafting elements rather than a battle royale game, actually. This is mainly because unlike other battle royale games, Still Alive doesn't pit you against a ton of other players by dropping you and all the rest on a massive map. Instead, the map of the game is more of a sizeable "arena", much like the map you'd experience by playing MMOFPS or TPS games. You won't be fighting to survive against 99 other players (or more) either - there are only 5 players in a match and naturally, the last man standing is the winner.It adopts the class-based character system that Realm Royale uses, and hence, depending on the character you choose to play, you'll get a special class-specific skill to use in addition to your usual arsenal of weapons. These special skills can vary from getting to control a drone to activating a ghost suit which will effectively make you invisible for a short period of time.
Considering that Realm Royale has yet to be released on mobile, it is not surprising that Still Alive: Survival PvP manages to fill the demand for such a game on the mobile platform perfectly.
