Nexus War, a game with obvious influence from Urban Dead, is perhaps the greatest browser game ever. The only one I’ve played for more than a month (Started in July of last year).
In it, you do battle with other dudes, you craft weapons and armor, you cut peoples electricity, you build large barricades around people’s houses so when they wake up they’re trapped in a small square with no choice but to spend all their action points trying to break the barricades down.
Action points are used for just about everything in the game, from moving to hitting someone to death with a magical scimitar, and are gained every 15 minutes. They serve as a good way of making it so you don’t have much, if any, of a disadvantage if you only play every 12 hours, as opposed to someone that does something every 2 hours.
You start off as a mortal, something that’s more akin to an urchin than a warrior, gradually getting more skills as you level up, eventually reaching the second tier of classes, expanding your power and abilities, and then each second tier class has 2 or 3 exits. Once you’re tier 2, you’ll generally have the need to join a faction, unless you want to get hunted down and murdered in your sleep by people twice as strong as you.
The game is highly faction oriented, and it will serve a huge advantage to be in one. You have a stronghold, where you can sleep, you have a shared safe, where you can get items that other people put in, but of course, you can raid and be raided by other factions.
I myself got started with trial and error, but there are useful guides on the Nexus Wiki, like planning a character and stuff.
Anyways, I highly recommend it. Check it out, people!
(Orgh! Don’t know what categories to put!)
