Awful game. It claims to be like the original Leading Edge board game, but resembles it in appearance only - this coming from someone who used to own the original board game. This flash game used to be excellent, but whoever created it decided to destroy it. They have the talent to make a great game, but they don't understand what makes a game great. Playability is awful. 50s roll like 30s. 70s, 80s, and 90s roll like 50s, 60s, and 70s. Aliens now pop out of places they never did before to such an extent it borders on cheating. Newt gets stuck on the question marks three times as much as she did in the actual board game, leading to infuriating results. Enter the final level with eight marines (maybe even fewer now, I don't know for sure) and way too many aliens come so that it is literally impossible to succeed given the limited number of moves and ammo. Just swarm after swarm, making any forward progress next to impossible. It's really a shame, too. It used to be really great game, but the creator doesn't realize that games are supposed to be FUN. Yes, games need to be challenging, and this one used to be. Now it's unplayable. I wasn't going to write a bad review since the game is free, but it just got too ridiculous.
