Just a post I made elsewhere, maybe some of you guys will find it interesting.
I've started this mod as a peaceful player. I flocked the everyone I saw, and they accepted me. Until a guy on a Russian server put a bullet in my head because he liked my 1911. That made me realize what exactly this game is, it was definitely not L4D as I thought. It was the other players I should be afraid of.
After that, I avoided players and cities. I went north, scourged the barracks, got military gear and kept getting more. I found some TacticalGamer guys and even hung out with them. Until one day a bandit shot me, all my hours went waste. Then I started to change.
I just had my first intentional kill last week. It felt awful, I wrote a huge block of text about it. I know this is just a game, but it felt really bad. I sweated, tried to convince myself to do otherwise but I did it anyway. I killed another one(bandit) shortly after him and got killed after that. Frankly I deserved that.
Then I started to hang out with my friends. It's much different with friends, suddenly everyone else became a threat/opportunity for us.We have a shoot on sight policy for people wandering too close to us. Save for those poor guys with makarovs, but we rarely see them(we always play up north, near the NW airfield). Since then I probably killed 5-6 players in total. Some of them were panic situations though.
We're extremely well armed, with guys in dedicated roles like a Marksman with DMR(me), another marksman with M14 ER1, Assault rifle guy with M4 Holo M203 and another "stealth" guy with M4 SD. We still need stuff like NVG's for some members, barracks are too dangerous so we try to get them from other players.
Today, we found a nice position overlooking Stary Sabor camp and set up our sniper nest. After a good 20 minutes, one of our spotters spotted a guy in ghillie suit, sneaking around the camp. Unluckily he attracted a zombie so he was pretty distracted. When he stopped to shoot the zombie, I took my shot and killed him from 300 meters. He had awesome gear, a complete SD set (M4 SD + M9 SD) GPS, NVG, big Coyote backpack, 7 mags of SD STANAG and another 7 for M9. I probably wasted his whole last week. It was totally worth it for us though.
The thing is, as you get off the coast and get good gear and become one of the "northerners", there isn't much else to do than look for the best gear possible and come up with creative ways to kill other players. So you eventually have to do it, like it or not. You pass the "training mission" of zombie survival and then it becomes a dream ArmA 2 PvP mission.
