Platinum trophy. Delta Difficulty

This game is effectively a stealth shooter. I expect and prefer to play this game as an open-world over-the-top supersoldier type shooter but Crysis isn't that. It's a very slow open forward moving tactical shooter with a lot of the same mechanics you'll find in those types of shooters.

However, a high point in this game is at the end of Chapter Relic. You come up to a landing zone deep in the night of the jungle, but there are enemies around and you don't know it. These enemies have the same capabilities as you, they're 4 Korean soldiers with nanosuits too. You don't know this yet because they aren't showing up on your radar until they turn off stealth mode or start shooting. At this point, I had this very predator-style back and forth where I was sneaking slowly while they were sneaking slowly and I kept baiting them by throwing grenades in open areas and then resuming stealth mode so they would think I was in that position, and they would attack there, allowing me to ambush them.

There's a huge bug in the mission Awakening where you can't see through the sniper scope or the visor when you reach the part where you fight the Koreans in nanosuits.

The final few missions where you fight the aliens are so shit that they completely change the pacing of the game and this game probably has the worst final boss in FPS history. In essence, there are only two alien types - the smaller ones and the bigger ones. They're both airborne-only enemies, and the missions where you encounter them tend to have much smaller maps like the aircraft carrier, and the enemies are bullet sponges that don't have any hit reactions so you're expected to use the stronger weapons such as missile launcher, gauss rifles, and miniguns. It's too bad that these encounters are shit compared to the sandbox nature of all the previous missions. The small aliens can only bum rush or shoot you while the bigger aliens just fly through the air shooting you from blind spots. They're such an aggravating enemy group to fight in comparison to the human + nanosuit soldiers that could do so much more such as flank you, throw grenades, enter stealth mode, use vehicles, etc.

The game has two real boss fights: the Korean general and the massive alien platform. Both are shit. The Korean general is a nanosuit soldier who isn't wearing a helmet but is a massive bullet sponge. Before the fight, you're knocked out and lose all ammunition so you have to use the pistol + SMG in the small room while the general has a minigun. He just eats everything while you scavenge for ammo.
The giant alien at the end of the game is the worst final boss of a shooter in recent memory. It's divided into 4+ different stages. First is an alien walker that you need to shoot with about 12 missile launcher shots, yet it has no hit reactions or health bar to tell you if you're doing anything to it. Then the real boss starts and you have to take down parts in stages while fighting waves of the aforementioned big flying aliens. Crysis is not frenetic nor fast enough of a game to constantly deal with that many enemies on the screen at once while being shot by a massive alien using a freeze ray and big explosions.
