I just finished Abuse - I didn't realise how close I was to the end after my last play session. Saying that, I don't think I got the perfect ending...maybe you have to complete it on a higher difficulty level?...but I'm not going to go back through the whole game again. In my version the main character dies at the end, but I've seen a YouTube video of him surviving. Ah well. Abuse is a fun game - it's one of those where your keyboard controls the main character, and the mouse aims the weapon. It was the first game I remembered playing like that back in the day. It was also released in the days of shareware, so you got a slice of the game for free and had to pay to get the rest. The graphics are very dark and gritty, and the game very much plays on the shock card, with aliens jumping out at you from walls when you least expect it. Oh, and when I say aliens, I do mean 'Aliens', the game really wears its influences front and centre. It's very fast-paced and fun to play, but the monster designs do get a bit samey - you're essentially fighting a single palette-swapped alien creature for the vast majority of the game, with a few other enemies thrown in every now and then. Your main guy has a bunch of weapons at his disposal and a few power-ups, such as fast running or flight, and these are used to navigate the levels. Most of the levels are pretty easy to find your way around (unlike Marathon...grrr), with destroyable walls being the only real 'puzzle' element. It's a great short and sweet blaster, though, and doesn't overstay its welcome.
Next up on the randometer is...Jamestown: Legend of the Lost Colony. It's a modern-ish shoot-em-up. Sounds like it has bullet hell elements, which rather terrify me. I've never been any good at those, so we'll see how this one goes.
