Whenever the Survival Games starts, ALWAYS go for the chests that the other players aren't going for. Usually, go for the chests in the back and not in the front. This is what I always do and I usually get a lot of stuff this way! :)
Another good step is to be quick before any of the other more noobish players get to the other chests. Like the first step, don't go for the chests all the other players are going for. If it's a more harder trip then to the other chests that all the other players are at, don't care. It'll all be worth it in the end. When Grace Period starts and all other players are LOOKING for players to kill, do the opposite. Run around in a unpopulated area and maybe try and find some chests that the other players didn't find first. Wait until there's just a few players remaining, before you go exploring for some prey. I'm sure you've already heard a lot of this stuff already (maybe) but I still wanted to point it out anyway! :P
There is a glitch to get into Survival Games with the stuff you have outside of the game but I still not tell you how to do it. I already wrote a blog about how to cheat in Survival Games and it got removed by a Moderator! :(
I will tell you that if you ever DO find a diamond armored player killing all the rest of the Survival Gamers, don't come anywhere close to him. Hide and wait until he kills are the other Survival Gamers and then win. Never try and take him down! It never works! You could also report the cheater in Survival Games and ask a Staff to teleport to you! Another thing, I hardly ever do team in Survival Games. I do good in Survival Games with or without a team member. I really think that teams in Survival Games slow you down sometimes unless your team is a really good Survival Gamer, but all of the other people I've teamed with in Survival Games always slow me down and it's harder to win! :(
