This game will make you grow hairs on your chest...regardless of what sex you are.
John Mullins is an actual SOF; getting paid to rid of all the evils from this Earth. Why? Because he's tough, with means you (the reader and quite possibly the player) are tough. Tough but polite. So polite you can sneak in Saddam's palace and excuse yourself to take his 'right hand man' General Amun into questioning. Yes, questioning.
Your main mission? To capture and locate the terrorist group who stole 4 nukes. Why is this concern for you? Not much. After all, you are a nuke anyway. Error: you are THE nuke. But 'The Shop' doesn't know this. The Shop doesn't know much anyway especially your main friend Sam (who by-the-way never washes his clothes as he always wear that 'Harley-Davidson' T-Shirt and cracking jokes like 'Remember the C4 incident with Hudges?' which you wish to reply 'nope' or 'Who Hudges anyway?'. But replying 'no' isn't tough anyway so you let Sam giggle).
What's heading towards Herculean proportions is that you earn loads of cash for your troubles. After all, you are a SOF. So what's the cash used for in this game? Squat all. Now that's tough.
The sound quality is extremely tough. Every weapon, even the silent ones will cause your 'PADD' rating to climb up, hence more 'spawning' of enemies. Does this make sense? Not really. However you don't care anyway. You're tough. Go ahead and mow down 465 yakuzas in the fire escape staircase. You don't question where they arrived from. Neither does anyone else, including Sam.
What's no-so-tough is the music score. Pretty lame in your opinion. You wish it was something from Quake 2.
Speaking of Quake 2, the game's graphics derived from a heavily modified Quake 2 engine. Tough? You bet.
Overall, it's a tough game. Can you take the heat? No? Go away and write a novel about some sniper named 'Iceman' and a team leader named 'Tracker'...
