Hi, I've been gaming/modding since about 1983 (yeah, Major old school), and I had a few games released commercially in 1984 for the Oric-1 (48k ram, 1Mhz cpu). In the 90's I did mods for Duke3D, Quake & HL, and then in 2001 I did a mod for 'Severance: Blade of Darkness', which won a PCGamer mod competition (a GeForce3! :D). I'm now working on another mod for Severance (without a time limit this time) which I hope to get finished this year (2010).
In Tutorial Mod the enemies use the original game's combat logic, so groups won't all attack at the same time.
