G'day, I just tried running your geoscape replacement alpha thing and it ran fine so I decided that I should give you my specs in case you wanted to know what hardware. Pentium 3 - 800mhz 64MB Geforce 2 MX 400 DDR 512MB RAM PC133 VIA CHIPSET Windows XP Pro And for the alien ships crashing in water and having water missions, I'd like to say, doesn't Elerium detonate when it's combined with water and that's why the alien ships didn't survive?
