First I've heard of it, achievements have just appeared here:

Seems it will have a variety of modes, including Waves from the PGR4 game.

Are there any denizens of this august 'froup interested in a
get-together for Halo 3 gametypes you don't normally get to play in the
social matchmaking lists?

Ceri's become addicted to the objective type games, but also has a soft
spot for Oddball and its variants - which aren't on the Social Skirmish
playlist.

As we proved with Man of Kent last night waiting for DBSnappa to finish
GTAIV, even with just three people Oddball is massive amounts of fun.

Between 7pm and 9pm would be best for us, so if anyone wants to join let
me know and I'll get some custom games going.

Quite a few of us still need to start off on these league matches
I propose we agree a day & time where the majority of us can make it online
& play as many games as possible?

Friday 9pm?

Don't know if there was anyone gonna do this, so I've jumped in!

10th Frame (C64). Ten pin bowling, but with a touch of realism. I think
it was by the same people/person that did the leaderboard golfing game.
Wasn't too bad, but didn't have the depth of gameplay needed to keep my
attention for too long.

3d Construction Kit (Amiga). I did have the C64 version, but due to lack
of memory it was a bit restrictive. I moved onto the amiga version later
and it was much better. I recreated such exciting places such as: my
flat, my street, my mam's house. Then I added hidden rooms.
