Back in 2007, Crysis felt like a game from the future. Running on a top-spec rig, no other game could compete. Hell, very few PCs could even run it at anything above medium settings, and even today the game is still being modded and tweaked to look more impressive. At the time, it's safe to say that a console version of Crysis didn't look likely. Then the CryEngine 3 was developed with consoles in mind, Crysis 2 was released to critical acclaim, and we now have the original game running on that new engine.
This is the same game we got what seems like eons ago, sans one level no one really liked in the first place and a multiplayer mode no one would play. The missing content might be seen as a bad thing by some, but this is a downloadable title that costs less than £20, delivering a campaign that's easily good enough to stand as a full retail release. The excluded level, Ascension, saw you flying a VTOL around the jungle, and proved to be a sore point for many players of the original PC release. It's safe to say it's not missed here.
Crysis sees you step into the shoes of an elite soldier in the year 2020. The members of Delta Squad are seen as special enough to wear a new high tech nano suit, and this allows you to become a superhero of sorts. Depending on the situation you can gain extra armour, more strength, increased speed or a Predator-like cloak. It's all very futuristic, and the perfect tool to give you the upper hand on the North Koreans who serve as your enemies in the first half of the game. The latter are holding some archaeologists hostage on the beautiful island you've been sent to investigate.
While you're given primary and secondary objectives, how you go about getting to each location and completing each task is up to you, and will likely depend on your play style. The way the game lets you tackle each scenario differently is the key to its success.
If you're a cautious player you can go down the stealth route, moving through the undergrowth and using your cloak to get up close and personal before dispatching enemies one at a time. Unluckily for you, the nano suits aren't perfect. Firing a weapon will de-cloak you, putting you into a rather sticky situation if you don't take out the enemies quickly. It also drains quicker if you're moving fast. So crawl along the floor and you can stay cloaked for ages; run, and you've got a few seconds, max.
Alternatively you could go all Arnie (pre-government) and tackle your objectives head-on, running and gunning into battle. Switch to maximum armour and you can take more hits, but this option really isn't advised unless you're able to headshot enemies without breaking a sweat. Given that the later Korean soldiers in the game wear strong armour, you'll be restarting from the last checkpoint rather frequently if you're unable to snuff them out quickly.
Your weapons can be modded while out in the field, so as long as you've got the gear you can effectively act as a one man army. Sniping from distance is always a good way to dispatch patrolling guards, before donning the cloak and walking slowly into the base. From here you can take your time, taking out soldiers, moving from cover to cover. As long as you don't get too close or let them see you, you can take on large armies without too much bother. You've got to be careful though, as one slip up will mean death or a hasty retreat - most likely using your suit's speedy powers.
