A walkthrough of the ZX Spectrum game, Kentilla. From the recording originally sent to http://www.rzxarchive.co.uk/. Recorded using rollback, a feature of the emulator which allows you to mark a point, which you can then roll back to later if you get in trouble, and try again.
The lightweight, portable Javelin offers stand-alone surveillance to observe opposing forces. Javelin is a man portable anti-tank weapon with a carry-weight of 22.3 kg. The CLU is easily attached to the missile and launch tube assembly. Javelin automatically guides itself to the target after launch. Javelin in operation with the Irish army.
Confidence votes 217. There are a few that use lighter weights, even 14 grams, and some that use heavier, around 30 grams. However most professional dart players use from 18 to 23 grams. It's best though to throw what you're comfortable with. I myself use 26 gram darts.
