I remember beating Resident Evil 2 with my friend all the way through Leon's campaign. Nothing like soda, unholy amounts of goldfish crackers, and zombies to spend the night.
That same night we also got the international liscence in the first Gran Turismo.
Holy crap that was hard. It took us forever to get that cause we sucked.
Beating the original Ghost Recon games. I don't know why, but those were some really intense moments that I felt proud to survive through.
I remember in Counter Strike (the old one), I was playing terrorists. I happened to be the last remaining survivor and there were about 5-6 CT's left. It was a good thing I still had most of my ammo and all of my health and kevlar along with some flashbangs and a grenade. The map I was playing was de-Dust. The bomb was in the halls, that is located in the middle of the map. Knowing that the CT's were most likely camping the bomb, I popped a flashbang in the hall, managed to pick up the bomb and kill a couple CT's. Popped another bang, which kinda blinded me, but managed to reach the bombin area. I quickly planted and fought off the remaining CT's. There were about 4-5 of them left, all firing at me. I managed to pop a grenade, which did nothing, and took down two before I went down. The CT guy tried to disarm, but kaboom~! He got rocked.
Battlefield 2, I got the Sergeant rank. But then got bored with the game.
