The choice of weapons in Shadowrun is typical but rather limited. Each player has access to a pistol and two grenades by default, but can purchase an SMG, rifle, shotgun, sniper rifle, minigun, rocket launcher, or katana. Yes, you read that correctly, a katana. Counterstrike has the AWP for cheap kills; Gears of War has the chainsaw for cheap and annoying kills; and now the weapon that people will complain about in Shadowrun is that friggin' Japanese sword.

It is a powerful melee weapon - even a troll can be taken out in just a couple of slashes - and can be used for some nifty stealth kills if you can sneak up behind an opponent with it. Catch him off guard and you get an instant mortal wound which will kill the character if he doesn't get to a Tree of Life for healing and quickly. The dwarf race is immune to this attack, by the way, so don't try to stealth kill a dwarf with the katana. It won't work.
Despite its lack of depth, Shadowrun is tons of fun to play online and, as with any team-based FPS, a skilled team working together will always succeed over a bunch of guys just running around and shooting. There is enough variation in the combination of magic and tech skills to keep the game interesting over many rounds of play. Players can purchase as much magic and tech as they can afford, but can only equip three such skills at a time, again bringing strategic thinking into play. Some abilities are more suited to one race than another (although any race can use any ability) so how ability will affect your character's race is always an important consideration.
Troll players will want to take advantage of their size and strength by using the huge minigun (that sounds like an oxymoron, but the minigun really is the biggest and heaviest weapon in the game) or rocket launcher. Neither of these weapons is the most accurate, however, so trolls will probably want to equip Smart Link, an ability that helps make aiming easier. Doing so means that there's something else they may want but be unable to equip, however. Nearly all the abilities are useful in different ways, so players need to think strategically when deciding what to use. Fortunately the game allows teammates to share funds at the start of a match as well so they can help each other purchase the skills that will best serve the team as a whole.
I have to detract points from the game for a few flaws. The aforementioned lack of a single player campaign is pretty much inexcusable in my book when you're charging sixty bucks for a game. One player I was teamed up with described it perfectly by saying "I bought half a game for sixty dollars." It's frustrating, but true. Also leaving split-screen play out of the mix is a big detriment as far as I'm concerned. I have two teenage sons and, like many families I'm sure, we play games together. While we can all play Halo 2 at the same time and two of us can play Gears of War at the same time, we have to take turns individually if we want to play Shadowrun. My fourteen year-old summed the situation up as only a kid can by saying "it sucks." It does.
